The Sludge King is the main antagonist in Sludge King: Part 2. Felix first saw him in a computer animation where a computer-animated version of him fell down the sewers and was captured by a computer-animated Sludge King.
In Part 2, ever since his daughter moved out of his castle, he captured Rosco and Felix with a desire to eat them. However, Felix used a remote from a family who was watching the cartoon to literally rewind it back to the moment where he saw the computer animation, saw what happened next, and reenacted the gag: he convinced the Sludge King to drink enough grog to use a portable outhouse, then escaped with Rosco.
Appearance[]
