Bumpy

A wacky little sock-eating bed monster who comes from the ABC claymation series, Bump in the Night. He first debuted in SpongeBob and Friends Find The Black Cauldron, where he was a slave to the horned king for eating the horned king's socks, and was condemned to sing karaoke in the mess hall for the human minions of the horned king. He help Spongebob and friends take him down, and it is assumed he return back to his world afterwords. He didn't appear much in the episode though, due to Scroopfan's tendency to get distracted with other matters in the series.
