Slobbers are giant Blotlings in Epic Mickey and are the Shadow Blot's henchmen. Once he starts inhaling, Mickey must choke him up with Paint or Paint Thinner. His claws will damage Mickey so violently. They have the form of Oogie Boogie from The Nightmare Before Christmas. They are mini-bosses, but act as a common enemy.
If Mickey redeems him in Tomorrow City, he gets Goofy's Torso and what Tomorrow City looks like, but if he defeats him, he gets a gold pin, but can't get both in a run, as with many other things in the game.
The Slobber in Tomorrow City probably works for Mister Rover or Petetronic.
