Shrinking ending
>Brainstorm gets ringleader out of his panties and loses weight
>Ringleader does magic, but has fooled brainstorm into thinking he'd actually restore him to normal size
>Poor Brainstorm gets so nervous watching the world around him get even bigger and bigger, until he's even smaller than a grain of dirt
>The ringleader levitates him to his new home, in a petridish, under a microscope, as the smallest mare in the universe, alongside other small things that are really gigantic compared to him, like a grain of sugar
>He's not alone, as he has to share room with Amoebas, ponies pay good money just to see him
>Eventually they some how make good friends, and find a way to make the ringleader sick, so he has no choice but to restore Brainstorm to his normal size
Panties ending
>Ringleader never agrees, so he stays in Brainstorm's panties
>Brainstorm becomes more and more of a solo act, being "The smallest, fattest mare in equestria", singing to a loving audience
>Every so often, the ringleader will make big movements and tickle him, making him make a low pitched, feminine giggle
>Of course, being in panties, he has to deal with Brainstorm occasionally passing gas, or getting trapped in his anus
Blueberry
>Brainstorm gets ringleader out of his panties and loses weight
>Ringleader convinces Brainstorm to do one last show, which he agrees to
>The show goes as normal, until the Ringleader does one spell on brainstorm, increasing his size to a good centimeter or 2... and turning his red polkadotted dress into a blue polkadotted dress
>"Wh-what's going on? I thought you were restoring me back to normal... I feel all weird" Brainstorm says as he turns a darker shade of blue
>"Well, I've been thinking, you are blue, and have a green mane, I always thought you'd make a good blueberry" the ringleader says as brainstorm expands
>"M-make it stop!" Brainstorm screams as he Turns spheracle right in front of the audience
>"I'm afraid you're going to be like that from now... of course you're going to have to be squeezed... or you will explode" the ringleader says
>"O-oh no!" Brainstorm says as he becomes more and more helpless, and the flea sized ponies roll him around for fun, singing about blueberry brainstorm
>Poor brainstorm feels like he could pop any second during the musical number
>They finally do hook up a juicing machine to him right at the last second
>From now on, Brainstorm is the amazing and mysterious, half mare, half blueberry, treated as a juice source and ball for every show
