After watching "The Toxic Fandom Game Show" by The Warp Zone, I am hoping to see a series of it. Here are the contestants I want in Episode 2: Mario (Super Mario), Dipper Pines (Gravity Falls), and Twilight Sparkle (My Little Pony: Friendship Is Magic).

The questions I want to see are:

Which fandom was poisoned by a fanfiction about one of its main characters going to a Taco Bell restaurant? ||Gravity Falls; Dipper Goes To Taco Bell||
Which fandom has an entire fanfiction website dedicated to the "bronies" and "pegasisters" in that fandom? ||My Little Pony: Friendship is Magic; Fimfiction||
Which fandom is responsible for the majority of fan art of transformations from a certain crown power-up? ||Super Mario; Super Crown power-up||
Which fandom has tons of cryptograms containing secret messages? ||Gravity Falls||
Which fandom is responsible for the majority of fan art and fanfics of its characters in diapers? ||My Little Pony: Friendship is Magic||
