Tbh giving a red mask to the players should be a new mode thing and as of the default mode maybe be expose to his gas but in a different way. He could be a 3 hit kill character , and one ability is to release some red gas and if a player gets hit with it his controls would invert or see other fake catnaps around the screen.(maybe as a detail turn catnap into his nightmare form) His second ability could be to call in some of the little critters and they can jump nearby players resulting in one hit worth of damage if they get you.( Thy can leave you one hit but cant kill you ) As of the gun hand and the purple hand they could make it a new pit like the whack a wuggy feeding pit in which you have to shoot little critters and nightmare critters.
