He floats around, sneezes a lot, and gets his VERY demonic slime all over everything. He also bad-mouths Glomp.
How to unlockEdit
You must beat Classic mode with Ao Oni Worm, Emoji Moon and The Grassy Head from the Underworld on Intense difficulty. Then you must beat him at Distorted Swamplands.
He will sneeze demonic slime everywhere on the screen (covering it with the slime) and all players will die.
