The 3 of us deal with the worst mentor ever who may possibly be a Time Lord

in episode 18 of Digimon Adventure, "The Piximon Cometh" or "The Fairy!

Picklemon!"  This time around: Digimon death count is at 6, Joe is a secret

racist, Piximon refuses to feed starving children, Tai taught himself to

ride a bike (literally), invisible dinosaurs, Piximon actually lives inside

a TARDIS, and Gomamon uses his interdimensional fish powers to cook dinner.
