Aaahh!!! Real Monsters - Season 2 - Eps 1: Spontaneously Combustible
Ickis is diagnosed as spontaneously combustible -- which means he could explode at any moment. His friends feel sorry for him, but at the same time are reluctant to be near him for fear that he could "go at any moment." The Gromble refers to the Academy monsters as "humans" because they are afraid of something they do not understand.
