Yeah, that anime episode is brilliant. Looks great how they did it as an anime cartoon. Is that the one where Butters gets a ninja throwing star in his eye and they dress him up as a dog and try and take him to the vets so their parents don't find out
My favourite Mr. Hanky episode is the one in season 4 (I think) with his family and the rip off of the song from Lion King. That was hilarious.
