Twilight and Sunset finally finished painting and returned to their bedroom. They had needed to take a dump really badly by the time it was over, but they had both made it, though the bathroom they had used was out of toilet paper, thus making their underwear even dirtier.

That night, the Dazzlings stood behind the pillars in the entrance room of the castle, waiting to ambush the girls as they tried to escape.

On the third floor, the eight Equestria Girls met up, and walked over to the garbage chute.

"Are you sure this don't lead to a trash compactor?" said Applejack.

"No, I'm pretty sure it leads to a dumpster," said Princess Twilight, who smelled nearly as bad as Rainbow Dash.

"Isn't there any cleaner way out?" said Rarity.

"There isn't," said Twilight.

"You'll still be cleaner than me," said Rainbow Dash.

They slid down the garbage chute one by one, and into the dumpster. It was full of rotten garbage. The girls climbed out.

"Where are we going?" said Fluttershy.

"We have to cross that forest," said Princess Twilight. "If what Sonata said is true, across it is the sirens' dark crystal. If we destroy it, we'll have our power back."

"And we can kick Aria's butt!" said Rainbow Dash.

So, they made their way toward the forest.

"I gotta go pee!" said Pinkie Pie.

"I do too," said Princess Twilight.

"Now?" said Sunset.

"There's a bush over there!" said Twilight. "I'll use it real quick."

Just as she was walking over to the bush, she heard shouting, and looked. A chariot was approaching, with Fartsparkle pulling it, and all three sirens riding it, Aria in the center.

"AAAAAAH!" said Princess Twilight, and she ran back to the other girls, wetting herself yet again. "The sirens are coming! We have to run, NOW!"

They ran toward the forest as fast as they could. The sirens were catching up, but the girls reached the forest first and strayed from the path a bit, running through the trees.

The sirens' chariot reached the forest path, and Aria got Fartsparkle to stop running. The three sirens dismounted and searched the forest for the girls.

"Come out come out wherever you are!" said Aria.

Rainbow Dash and Applejack were hiding under a spot of land. Pinkie Pie and Fluttershy were hiding in a tree. Both Twilights, Sunset, and Rarity were hiding in a bush.

Pinkie Pie still needed to go to the bathroom, and held it in for as long as she could. As Adagio was walking by the tree, Pinkie couldn't hold it any longer. She peed in her shorts, sighing of relief. The pee trickled down on Sonata's head. She looked up, and saw Pinkie wetting herself in the tree. Adagio kicked the tree, and Pinkie and Fluttershy fell out, Pinkie landing on her butt. Fluttershy quickly got Pinkie over her shoulder and ran, not caring that some of Pinkie's pee got on her.

Fluttershy moved a tree branch out of the way as she ran by it. The branch smacked Adagio in the head and she fell down. When she got up, there was no sign of the girls.

Sonata sniffed. "I smell Rainbow Dash!" She followed the smell of pee, farts, and poop, and found Rainbow Dash and Applejack. Applejack kicked Sonata in the shin, and as she hopped on one foot, Applejack and Rainbow Dash ran.

Aria searched for the girls, tiptoeing by the bush that the Twilights, Sunset, and Rarity were in. She sniffed a bit, and Princess Twilight froze, sure that Aria could smell her in the state she was in. Aria walked over to the bush, sniffed some more, but then dismissed it and walked away. Twilight, EG Twilight, Sunset, and Rarity let out sighs of relief.

Then, Rarity accidentally farted loudly. Aria turned toward the bush, and found the four girls inside it.

"Really, you couldn't hold it in?" said Sunset.

Rarity blushed.

"I've got you now!" said Aria.

Princess Twilight was so nervous she accidentally farted, wetting her panties a little more.

"Run!" said EG Twilight.

The four girls ran, and Aria chased after them. Princess Twilight grabbed a banana off a tree, peeled it, and threw the peel behind her. Aria slipped on it and fell on her butt. When she got back up, the girls were out of sight.
