Later that day, after Rarity when she was invisible, pushed Blueblood in a pile of mud, and after all the Mane 7's school classes are over, the Mane 7 were now ready to go home. They have just walked out of the school hallway, and then out of the school. The Mane 7 were now standing outside, talking with each other.

"Well, it was nice that Blueblood cancelled his idea, of a private spa, huh?" Rainbow Dash said, happy that Blueblood was out of the way, he has just recently forgotten everything about making the private spa, in place of the animal shelter.

"I am indeed thankful, that the animal shelter stays." Fluttershy said, also happy that the animal shelter stays as it is.

"I couldn't laugh more, than a hyena, when i saw Blueblood covered in mud." Applejack chuckled.

"I should have brought my camera! That would make a nice spot, on my picture collection." Pinkie Pie snickered.

"I'm just happy that this ruffian got what he deserved." Rarity said, satisfied about her revenge against Blueblood.

"That's good to hear." Sci-twi said, before beginning to look serious. "Now we just need to find out, about my potion's fate." She said, getting the others attention.

"So Twilight, what do we do with the potion?" Rarity asked her.

"I don't think i should be the one keeping it. Maybe we should just throw it away." Sci-twi suggested.

"No offense Twilight. But wouldn't it just be wasted, if we throw the invisibility potion away just like that?" Rainbow Dash said, while still having the idea of using some of it. The others gave Rainbow, a curious look. "I mean come on, Rarity has used it twice now. And we've not used it even once."

"I gotta agree with Rainbow Dash. This invisibility potion sounds fun." Pinkie Pie said, agreeing to Rainbow's idea. The others now begins to think about Rainbow's suggestion about keeping the potion anyway.

"Ya know, maybe Rainbow Dash has the right idea about keeping the potion Twi. Who knows, maybe it could come in handy for any of us." Applejack stated.

"I'm not sure, it's a good idea to keep the potion." Sci-twi said. "But do you insist?" She asked them. Pinkie Pie in respond, fell to her knees, and gave some of the most cutest puppy eyes, she could possibly make.

"Pleeeeeaaaaasssseeee." Pinkie Pie begged her. Sci-twi sighed in defeat.

"Alright, we can keep the potion for now. But we need to hold my invisibility potion a secret. Who knows what would happen if it came to the wrong hands." Sci-twi said to her friends, the others nodded in acknowledgement.

"I agree with Twilight." Sunset Shimmer said, agreeing to Sci-twi's paranoia about the potion. "Therefore, we need to be careful about using the potion."

"Yeah yeah, remember to be careful about using it." Rainbow said ignorantly. "Now give me a sample."

"Calm down Rainbow." Applejack said. "Anyway, the invisibility potion could be used, for me to get the eggs from my hen easier. Some of them could be quite aggressive."

"There are some animals, that are too shy, to be close to humans. I could go invisible, so i can see some of them personally." Fluttershy said eagerly, with the invisibility, the shy animals won't know that she can see them.

"I can go to any party i want. Or maybe watch Gummy while i'm invisible. Or maybe eating cotton candy. Or maybe play video games. Or maybe..." Pinkie Pie said, while continuing her long talk, about possible things she could do.

"I would rather save mine just in case. Who knows what would happen." Sunset Shimmer said, who would rather save her's for later.

"Me too. I have already been invisible twice." Rarity said. She has had enough invisibility for today.

"Don't know about me, but i should save it for later as well." Sci-twi said, not knowing what to do, with invisibility yet. Sci-twi then took out her water bottle with potion in it, out of her backpack.

"Alright girls, do you have a water bottle, or something? Where you can have a sample." Sci-twi said. The others responded by immediately taking out an empty water bottle, each out of their backpacks. Sci-twi poured some potion in each of their bottles, one by one.

"Oh yeah. Now i can become invisible too." Rainbow Dash almost yelled out, until she was shushed by Applejack. "Sorry, i was just really eager."

"Wheee... I'm so gonna have fun with this." Pinkie Pie said.

"Well, i better make this invisibility worth it." Applejack said.

"I don't like going around nude, but at least i won't be seen." Fluttershy said bashfully.

"Like i said, i'll save mine for later." Rarity said.

"Me too." Sunset Shimmer said in agreement.

"Me three." Sci-twi joined in.

"Well, i don't know about you, but i think i'm going for a little walk." Rainbow Dash said, while beginning to run off in excitement.

"See ya Rainbow." Pinkie Pie yelled out, but it was too late, Rainbow was already out of sight.

"That's Rainbow to ya alright." Applejack sighed, knowing Rainbow Dash really well, she would often do something like this, when she's either happy or eager. "Anyway, see ya later tomorrow. It's a special holliday tomorrow, so we're free to see each other there." Applejack said, while starting to walk home. Applejack's right about tomorrow, there is no school day there, and neither the next few days.

"Bye bye guys." Pinkie Pie said, while also beginning to walk home.

"Uhh... Goodbye girls. I need to check for some animals." Fluttershy said gently, she now also walked home.

"Bye darlings, i need to watch over Sweetie Belle and her friends today." Rarity said, while waving her friends goodbye.

"Bye Rarity. Bye Sunset." Sci-twi waved.

"See ya girls." Sunset said, while also waving her friends goodbye, and walking away from Canterlot high.

"Let's hope, they won't misuse it too much." Sci-twi thought to herself, hoping they won't misuse the potion.

Rainbow Dash was running through the city, and was thinking about, what she should do first, with the invisibility potion. Rainbow Dash was full of options.

"Should i do some pranks? Or spy on somebody?" Rainbow Dash thought mischievously, but couldn't really choose any of the options. Both of them were really good. She then hears a voice behind her.

"Well, if it isn't my old friend, Rainbow Crash." An insulting voice behind her said. Rainbow turned around, and saw a mint colored girl, around 18 like herself, wore a pair of blue pants, a shirt with a lightning insignia on it, and has yellow lighting themed hairstyle. It was Lightning Dust, Rainbow Dash's old rival. Rainbow Dash in respond gritted her teeth at her.

"Lightning Dust. So nice to see you." Rainbow Dash said sarcastic, and certainly not interested.

"I remember the last time we met, were i beat you in a little soccer fight." Lightning Dust boasted in front of Rainbow's face.

"Huh? Uhh actually, i defeated you in our soccer fight." Rainbow Dash said, she remembered the last time, they played soccer against each other, a few weeks ago, which resulted in Rainbow winning.

"Oh really? I don't remember that." Lightning Dust said sarcastic. "By the way, are you going to the beach today?" Lightning asked.

"No? Why are you asking?" Rainbow Dash asked her rival.

"Oh nothing, except that they're closing for a beach ball sport battle today. And i have been invited to join the beach ball game this afternoon. Along with lots of cider." Lightning Dust said, which got most of Rainbow's attention.

"Cider? I gotta join in." Rainbow Dash said, before she was silenced by Lightning Dust, who chuckled at Rainbow. "What's the laughter about?"

"Sorry, i forgot to mention, that only professionals are invited. And you certainly are an amateur in it." Lightning Dust insulted her.

"Ameteur? That's not true. I've been to many beach ball sport games." Rainbow Dash said with her excuse. Lightning Dust however ignored her.

"Whatever. Like i said, only professionals are allowed. And since you're not invited, the beach guards won't let you in." Lightning Dust said with her own amusement. She then decided to walk away, for the beach. "Catch ya later Rainbow Crash. I will enjoy the cider in your place." Lightning Dust said, while beginning to laugh afterwards. Rainbow Dash looked angrily at her.

"Lightning Dust really ticks me off." Rainbow said angrily. "Oh, i wish i could teach her a lesson." She said, before realizing something. "Wait... I can teach her a lesson." She thought, while beginning to give a slightly evil smile.

"Let's see how Lightning feels, to be unlucky today." She said, while heading towards the beach.

Rainbow has just arrived to the beach, and saw Lightning Dust was indeed right about the beach was closed, and had fences around it. She saw a poster nearby, saying that a beach ball battle, was going to happen in there, but only to those invited. She saw two guards watching over the entrance to the beach, they were big and strong. She then saw Lightning Dust appearing in front of the two guards. She showed them a special pass, and was allowed into the beach, Lightning Dust then walked into the changing room, to change to her bikini.

"Okay, now i need to get over the fence." Rainbow Dash said. She begins to climb up the fences, and thanks to her years of sports, she was easily able to climb over it. Rainbow Dash sneaked through the beach, and now begins to hide behind some big rocks, close to the beach water.

"Okay, now i just need for Lightning Dust, and her buddies to arrive." Rainbow Dash thought, while making her little prank plan. She then saw Lightning Dust exiting the changing room, now wearing a yellow bikini top and bottoms, which were both tied with small ropes. Rainbow also saw some other girls(which was probably Lightning Dust's friends) in bikini, exiting the changing room, which was a total of 3 more. They were soon ready for a beach brawl.

"Alright. Time to go invisible." Rainbow Dash said, while taking her water bottle out, and took a few swigs from it. Once she was done drinking, she put her tongue out in disgust.

"Rarity was right. It tastes disgusting." Rainbow said in disgust. Now Rainbow's blue body, and rainbow hair begins to disappear. She was now just Rainbow's clothes floating around.

"Perfect, it's working. Now i just need to take off my clothes, and i can begin my little prank." Rainbow Dash said mischievously. Rainbow started taking off her boots, and her stockings. Then she took off her white and pink skirt, followed by her blue coat, and her yellow shirt, with a rainbow insignia on. She pulled down her panties, and then unzipped her rainbow bra. Lastly, she took off her wrist bands. She left all her clothes behind the rock.

"Great. Now this is gonna be fun." Rainbow Dash said, with an evil(but invisible) smile. She walked closer to Lightning Dust's group, and hear them talk.

"Oh, this is gonna be fun. A beach, all for ourselves." A bikini girl with green skin said.

"Enough talk already, let's just begin the beach brawl." Another bikini girl with black skin said.

"Oh, i wish i could see Rainbow's face. She would be so jealous, that i not only get a beach for myself today. But also lots of cider for me to drink." Lightning Dust said, she was hoping she could see Rainbow's face. But she don't know that Rainbow is much closer than she thinks.

"We shall see." Rainbow Dash said with a smile. Then the beach brawl started, Lightning Dust's group was spitted in two teams, and the opposing team started.

"Alright. Heads up!" The girl with the ball said. She jumped up, and begins hitting the ball to the other side.

"I got it!" Lightning Dust said, while jumping up, and was about to hit the ball.

"Not." Rainbow Dash thought, and then ran close to the ball, and hit it away from Lightning Dust, just before she could hit it herself. The ball landed on the ground, and both Lightning and her friends got confused.

"Huh? Lightning Dust, why didn't you hit the ball?" Lightning's partner asked.

"I was trying to, but the ball slipped away." Lightning Dust excused. "Anyway, let's continue." She said, now ready to play again.

"Yup. Let's continue." Rainbow Dash thought, with a smirk. Lightning Dust was about to hit the starting ball to the opposing team. But then Rainbow interfered by weakly pushing Lightning Dust, who dropped the ball in respond.

"Come on Lightning. You could do better, than just let the ball drop down." The green girl said.

"I'm trying alright!" Lightning Dust yelled to her.

The game then continued, and Lightning Dust kept getting unlucky, due to Rainbow's interference. Whenever Lightning was either hitting the ball, or trying to start the game, Rainbow would always either weakly push her, or just hit it away from her hands. Lightning Dust became more and more frustrated.

"Wow Lightning. You sure are out of shape today." The black skinned girl chuckled to her.

"Shut up! Now i'm playing for real!" Lightning screamed out to them. But now Rainbow had another idea.

"Not it's time for the finale." Rainbow dash thought with a smirk. Just as Lightning Dust was about to jump, Rainbow Dash got a hold, of one of Lightning's bikini bottom rope. And when Lightning gave a big jump, her bikini bottoms were falling off her. Rainbow let go of the rope, so her cover wouldn't be blown, the bikini bottoms landed on the ground. Lightning Dust was silent, she saw her friends were either covering their eyes, or giggling at her, she even saw the guards, looking at her amusingly.

"What... What are you looking at?" Lightning Dust asked, then she looked down, and saw her bare pussy, and bare butt. Lightning Dust immediately gave a scream, and covered her pussy.

"Don't look at me!" Lightning Dust screamed embarrassingly, she saw her friends still giggling at her, and could barely hold their laughter back. She saw her bikini bottoms on the ground, and was about to pick it up, but then a small beach wave appeared, and took the bottoms away from her, much to her dismay.

"Nooooooo! Not my bottoms!" Lightning Dust said, while still covering her bare bottom. "Damn that wave. I forgot that it the beach waves more today. I'm changing back, and going home." Lightning Dust angrily said, while storming off back to the changing room. Rainbow Dash behind the changing rooms were laughing really hard.

"Oh that was just awesome! This invisibility potion is fantastic!" Rainbow Dash laughed. "Well it was fun, but i think i need to leave too." She said, while walking back to the rock. But when she came back, she saw only her boots, stockings, and wristbands. Everything else was gone.

"What! Where is my clothes?" Rainbow Dash thought in panic. She then remembered something.

"Wait, didn't Lightning Dust just say, that the waves were beginning to get higher today? Then that means..." Rainbow thought, and looked over to the beach water, seeing her other clothes floating in the water, and then sinked down.

"Oh no! I need to get them now." Rainbow thought, and was beginning to run into the water, but then her body begins to turn visible again.

"No. Not now." Rainbow Dash said, she was now visible and naked, right in the beach. She then saw the guards arriving, for beach patrol. Rainbow now had no chance, of getting her clothes back from the water now.

"Oh forget the clothes. I need to get out of here." Rainbow thought, she took her backpack, shoes, and wristbands, and begins to run over to the fence. She quickly climbed over, just before the guards could notice her.

"Did you see something?" The first guard asked.

"Nope, nothing but a nice ass from the lightning haired girl." The other guard said in a perverted voice. The first guard sighed at his perverted partner.

Rainbow was hiding in the alley, and was now thinking about how to get home now.

"Okay, i lost my clothes, but i can't use my invisibility potion to get home. I can't leave my other stuff behind." Rainbow Dash said, while looking at her 3DS in her backpack. She then looked up, and saw some stairs, up to the rooftops.

"But on the other hand. The roofs are unnoticed." Rainbow said. She climbed up a ladder, and walked up the metal stairs, until she reached the top.

"Oh yeah. This is just like playing Sly Cooper." Rainbow Dash thought. She jumped from roof to roof, there was not much of a distance between them, so Rainbow jumped over with a piece of cake.

"I wonder how the others are doing?" Rainbow thought to herself.

Author's Notes:

The next chapters, will involve some others, using the invisibility potion. Like Rainbow Dash for an example.
