Original Description:

While on a vacation to South America, Sunset Shimmer and Twilight Sparkle would come across many unique locals and people there who would share many interesting and amazing aspects of their culture. While at the beach, they would come across one individual who claimed to know a thing or two about a special type of magic. A type of magic that was unlike anything the two had seen before. Eager to learn more for the sake of research, the two managed to convince the young man to show them how to do it.

It was as simple as doing a quick chant, and blowing into one’s finger to make the magic happen. Fascinated by the results of this South American “Black Magic”, the two friends repeated the steps and blew as hard as they could into their fingers… Although, for being two of the smartest members of The Rainbooms, It was surprising that both of them failed to remember what finger they had to blow into to make this spell work properly.

Upon blowing into their thumbs, their bodies quickly began changing. It started with their hands becoming big as blown up rubber gloves, then their bodies becoming more bottom heavy and rounder, then their legs would stretch and wobble about, and so on and so on. And as they constantly changed into all kinds of weird and wacky shapes, such as this odd and balloon-like shape, the two of them, while shocked and surprised at first, eventually began to relax and enjoy. Even admire how odd and off the walls this whole experience was feeling! Perhaps they’re genuinely enjoying it!… Or maybe it’s the fact that they’re gradually getting dumber and dumber as a side effect of the spell… Oh well, at least their teacher is getting a good laugh out of it.

An old, but silly piece I never got around to uploading until now. A little Equestria Girls mixed with The Three Cabelleros, with a hint of my own little twists added in~
