CheeseHead BrownPants is an alter-ego of SpongeBob when he loses his memory due to amnesia. He appears in the episode "What Ever Happened to SpongeBob?" and is later mentioned again in the online game WhoBob WhatPants??? He also appears in the WhoBob WhatPants book.
He looks the same as the normal SpongeBob but wears a black hat with a purple stripe on it.
The people in New Kelp City call him this when they first meet him. Cheesehead is the mayor of New Kelp City, and cannot remember anything or anyone in Bikini Bottom when he returns.
- In the German version of "What Ever Happened to SpongeBob?," his name is KäseGesicht BraunHose which means CheeseFace BrownPants.
- Before he becomes mayor, he was called "Cheeseboy" by the citizens of New Kelp City.
- In English slang, CheeseHead also means idiot. So, his name can be meaning of self-reproach.
