Zipporwhill's Strange and Convenient Butt

The day passed relatively uneventfully. The fillies managed to make a large hammock so they wouldn't be sleeping covered in the critters Zipporwhill's butt ate and mostly talked about how much they missed their sisters.

As the sun was setting, Zipporwhill's abdomen made some grumbles that didn't sound all that good. Her eyes went a bit wide and she blushed. "Oh no, I need somewhere to go, really soon!"

Apple Bloom was about to get up when Sweetie put out a hoof to block her. "This one's my fault, I should do it. Scootaloo, have the bowl on standby and let's do this away from camp."

Scootaloo sighed and did as she was told. The 4 then trotted out to the latrine area with Sweetie helping Zipporwhill along; she wasn't too comfortable, making pained faces and slowly hiking her tail up as some early warning farts slipped out.

They got there just in time as Zipporwhill made pained grunts. "Oh, it's coming out! This is sooo embarrassing!" She squatted desperately while Sweetie Belle held her front, and out came a slurry of...chocolate milk and mini-donuts, broken only by farts that the fillies then realized smelled like strawberries.

Scootaloo rolled her eyes. "I'll catch it in the bowl then...and this is more gross than cool." She put the bowl under Zipporwhill, who was sighing pleasantly in relief. Scootaloo knew better than to look at the source of the diarrhea, but couldn't resist, and looked right at Zipporwhill's rear exit; the 4 tentacles had stretched outwards a bit to create an inner hole for everything to flow out of. Scootaloo was mesmerized, eyes and mouth wide, when a blast of strawberry gas sent a bit of chocolate milk directly into both. The orange filly instantly closed her eyes and spat it out. "Blegh...why me?"

After another 20 seconds or so, all 3 states of matter were fully out of the brown filly.

Apple Bloom broke the ensuing silence. "So...anypony hungry?"

Scootaloo gave her an evil eye with a bit of chocolate; a glare that, if looks could kill, would have disintegrated her and anything else in a 10-meter radius on a subatomic level.
