In CraftTG's Total Drama Transformation game, the final contestants had to mix a potion using ingredients they chose from a list, and then drink it. TF Central knew he needed to survive this game (as death was a real possibly), so that he could restore the dead and permanently transformed to normal using his magic.

So he picked harmless seeming ingredients:
Panties
A whole pizza
A flower
Hair from the camp's chef

He burned them all to ash and threw the ashes in a pot of water. Once he drank the concoction, the transformations manifested:
Ass Expansion
Weight Gain
Plant (a flower in his hair)
Femboy

Because he cooked the potion for over an hour, the results were super charged, resulting in a super heavy (especially in the bottom) very feminine TF Central who nonetheless was still a man. The other potions were either boring or lethal. so in an ironic twist of fate, Central, who wasn't even aiming to win, won the competition and by extension the entire game show season by pure accident!
