King Jellyjam

King Jellyjam is by far the smelliest monster ever. He smells so bad, he will die if he isn't clean. And he can't keep clean himself. He eats campers if they stop cleaning him or slack off from their work. He is one of the weakest monsters in all of Goosebumps due to him having two disadvantages: Can kill himself, and his only power is hypnotisim. He has appeared in The Horror at Camp Jellyjam.

Trivia

 * He is like the other blobs in the the Goosebumps series (Keith and The Blob Monster).
 * In the Give Yourself Goosebumps book "The Little Comic Shop of Horrors" a character named Milo is apparently able to make himself become the scariest being his victims can think of, and when he tries this on The Reader he becomes King Jellyjam, prompting a test of The Reader's memory, as he or she needs to defeat him the same way the real King Jellyjam was.
