Professor Pester holding a Hudsonite crystal.

Hudsonite is a green crystal invented by Professor Pester to strip away Hudson Horstachio's super powers he gained after licking a meteorite in the episode Super Hero Hudson.

The Hudsonite is a reference to the Kryptonite of the Superman DC Comics franchise originally created for use in the 1943 Adventures of Superman radio show, to allow the actors time to take breaks and time off from recording and acting.
