Now that the tooth hunt is complete, it is now time to see who got the most teeth.

"Oh yeah! That's what I'm talking about! We did this thing in ten seconds flat!" Rainbow Dash shouted. "Now, let's see who got the most teeth. It's for fun." said Pinkie. "Way ahead of you. Check it out." said Jack as he shows his bag of teeth. "Are you kidding me? That's not a lot of teeth. This is a lot of teeth." said Bunny as he shows a much bigger bag. "Gentleman, gentlemen. Let me show you how much teeth I've got." said North as he shows the largest bag out of all of them. "Is that all? Wait till you see mine." said Applejack as she brought out a wagon of teeth.

"Well, your wagon is smaller than my bag. I win. Yee haw!" North shouted loudly as he jumps around. But, he was too loud because the nightmare horses spotted them. Fluttershy turned around and gasped in horror. "Fluttershy, what's wrong?" Twilight asked. "It's the nightmare horses. They spotted us." Fluttershy replied. "Oh no. How did they find us?" Tooth asked. "Because they're everywhere. No matter where you go, you'll always see them." said Applejack.

"Come on, we got to catch them." said Jack as he flew off to catch the nightmare horses. "Right behind you, Jack!" Rainbow Dash shouted as she follows him. "Wait for me!" Pinkie shouted as she uses her party cannon to fly. "Guys, wait!" Twilight shouted. Sandy patted her on the back, telling her that he'll keep an eye on them in case Pitch tries to harm them. "Alright, but be careful Sandy. We'll be right behind you." said Twilight.

Sandy smiled as he flys off to find Jack, Pinkie, and Rainbow Dash.

...

The nightmare horses were found in Canterlot where they continued to spread fear and darkness.

"There they are! Let's show them who's boss!" Pinkie shouted as she uses her party cannon to blow away the nightmare horses. "Right back at you, Pinkie Pie!" Rainbow Dash shouted as she begins to attack the nightmare horses as well. As for Jack, he chased down one nightmare horse. Which he ended up succeeding by freezing it.

"Hey, I got one. Whoa, look at this thing." he said as he starts tapping it with his staff. "Way to go, Jack!" Pinkie shouted. Then all of the sudden, Pitch came out of the shadows and was right behind Jack. Pinkie noticed this and shouted, "Jack, behind you!" And then, she readied her party cannon to shoot him. Jack heard her and tries to strike Pitch with his staff, but missed.

"Frost? Is that how you defeated my nightmare?" Pitch asked. "Yeah. Why?" Jack asked. "I'm very impressed by your trick. It's a shame you chose those weirdos over me." said Pitch. "They are not weirdos! Who are you talking about? The Guardians or the mane six?" Jack asked. "Both." Pitch replied. Jack growled at him and shouted, "Just wait till I freeze your butt off for taking those teeth!" "Teeth! Why do you care about the teeth?" Pitch asked.

Before Pitch can go any further, Pinkie Pie began shooting confetti at him. "You leave Jack Frost alone! How many times do we have to tell you?!" she shouted. Rainbow Dash noticed what was going on and joined the fun. "Well, look who finally showed up. Now, I can finally give you the taste of your own medicine!" she shouted as she flew towards Pitch and starts punching him in the face. "Quite a puncher you are, Rainbow Dash." Pitch teased. "Just shut up!" Rainbow Dash shouted as she continues to punch the Boogeyman.

Pitch escaped by forming into a shadow and went to another building. "Hey, come back here! I'm not done with you yet!" Rainbow Dash shouted. "Oh, do you still want to play? You were too rough on me." Pitch teased. "Stop teasing us! You're being a bully!" Pinkie shouted. "A bully? That's not nice. I'm more than a bully, Pinkie Pie." Pitch teased.

Then all of the sudden, Sandy showed up right next to Pitch with a pout on his face. "Hey! Sandy!" Jack said. Pitch got startled when he saw the Sandman, but he got over it quickly. "Now, this is who I'm looking for." he said. "What do you want with Sandy?" Jack asked. "Let's just say I want to take away all of his sweet dreams." Pitch replied with a chuckle. Sandy got angered by this and brought out his sand whips to attack. He used them to swing Pitch in the air and made him fall to the ground. Pinkie was laughing really hard when she saw this. "Now that's what I call funny." she said. "Remind me not to get on your bad side." said Jack.

They flew down to confront the easily defeated Pitch, but he has other plans for them. "It's over, Pitch. Leave Equestria or else you'll be frozen like an iceberg." Jack warned. "You were right. It was stupid to mess with the dreams. I'll tell you what. You can have them back." said Pitch as he summons his nightmare horses to attack. Every single one of them surrounded them with no way out. "He can't quit, can he?" Pinkie asked. "Nope. I guess not." Rainbow Dash replied.

Pitch mounted on one of the nightmare horses and said, "Boo." The horses charged and were ready to attack, but Jack and Sandy fought them with frost and dream sand. Pinkie and Rainbow Dash fought them with a party cannon and martial arts skills. But then, the other Guardians and the mane six came to help on the sleigh. "Guys! Up here!" Twilight shouted. "Just in time, Twilight. We have a lot of nightmares to destroy." said Pinkie.

"Come on, we have to get Pitch! He's up in the sky!" Jack shouted as he and Sandy flew up in the sky to fight the horses. The sleigh followed the two and the fight with the Boogeyman has begun. "Finally." Pitch laughed evilly as he summons more nightmare horses on his enemies. "Let's do this thing!" Applejack shouted as she uses her hooves to punch each nightmare horse at a time. "Nice punch." said Bunny. "Thanks. I was born with this strength, you know." Applejack replied as she keeps punching the nightmare horses.

"I don't think my stare can get rid of the horses." said Fluttershy. "You don't need to. We'll just use our hooves and magic. After all, these creatures are made out of sand." said Rarity. "Oh, ok. Hop on." said Fluttershy. "Now, you're talking." said Rarity as she hops onto Fluttershy's back and joins the fight by zapping the horses. Twilight did the same thing with her magic, but it's more powerful and can destroy more than one nightmare horse at a time. Strangly enough, they did not see Pitch.

Where he was is right behind Sandy, readying his black sand arrow to shoot him. Jack noticed this and shouted, "We gotta help Sandy!" And then, he starting flying towards the Sandman. Twilight notices it too and follows Jack. "Sandy, watch out!" she shouted. Sandy couldn't hear her as it was too late to save him. Pitch already shot him with the arrow. "NO!" Jack shouted. "SANDY!" Twilight shouted. "Don't fight it off, little man." Pitch laughed evilly.

The others tried to get to Sandy on time, but they were blocked by the nightmare horses. Tooth tries to escape, but she fell back into the sleigh. "I'd say sweet dreams, but they're aren't any left." said Pitch. Sandy has gotten weaker by the black sand until he completely disappears. Sandy was no more. "Oh no." Rarity muttered. "Sandy." said North. "He's gone." said Bunny. "I didn't know he could do that." said Pinkie.

"No! NO!" Jack shouted in fury as he flew towards Pitch for what he did. "Jack, be careful!" Twilight warned. Jack didn't listen, he was too angry and wanted to get the Boogeyman more than anything. Pitch unleashed all of his black sand at the boy, but it didn't stop him. Jack pounded his staff onto the sand, causing frost to go everywhere and it exploded into smithereens. Pitch fell from this massive power and into the snowy ground below. But, the power caused Jack to faint as he begins falling. "Jack!" Twilight shouted as she uses her magic to catch him and bring him to safety.

Once she got back to the sleigh, everyone was worried about him. "Jack, are you okay?" Fluttershy asked. "How did you that? That was awesome!" Rainbow Dash asked. "I didn't know that I could." Jack said as he begins to feel pain. "Take it easy, mate. You gave us a quite scare." said Bunny. "I didn't save Sandy." said Jack. "It's alright. You'll be just fine." said Twilight.

On the ground below, Pitch watches the Guardians and the Mane Six retreat as he begins laughing evilly. "Finally, someone who knows how to have fun." he said.

...

Back at the North Pole, everyone is holding a memorial for the Sandman with candles surrounding his picture and holding hands.

Everyone attended except for Jack due to his guilt for not saving Sandy. He had his hood up and drew a picture of Sandy with his frost on the window. "Are you alright?" North asked. Jack said nothing to him as he gave him a sad look. "Come on, I know it wasn't your fault. You tried your best." said North as he puts a shoulder on the boy. "I wish I could've done something." said Jack. "Done something? Jack, you saved us from Pitch. Sandy would be proud for what you did." said North. "Are you sure?" Jack asked. "I'm sure. Your friends are proud of you too." said North as he gestures the mane six who came into the room.

"You feeling better, Jack?" Applejack asked. "I guess so." Jack replied. "You're still upset about Sandy, are you?" Twilight asked. Jack nodded his head yes. "Don't worry, we'll bring him back once we defeat Pitch." said Rainbow Dash. "See, Jack? You have us Guardians and your friends to guide you and help you go through this. And so will I." said North.

"Thanks North." said Jack. North reached out to him and embraced with a comforting hug. Jack hugged him back.
