Goosebumps (original series)
The Horror at Camp Jellyjam
King Jellyjam was formed when a careless camper left a cup of pudding or gelatin in a radiation-infested cavern (though it is unknown how he obtained the golden crown he wears). As Jellyjam grew, so did his powers. The purple, gelatinous blob was eventually able to hypnotize anyone, who came to Camp Jellyjam. But he was unable to leave the cavern he's in and hypnotism was his only power.
King Jellyjam also had a real foul stench (like a mixture of dead fish, rotting garbage, sour milk and burning rubber or boiling brussels sprouts) and sweated little black snails, instead of water. He often let out a humongous burp that shook the ground with its tremendous force. Since King Jellyjam's fingers were too fat and clumsy to pick up anything lying on the floor of his cavern, he was unable to clean himself. Instead, he hypnotized the counselors, including one named Buddy to bring forth the strongest, most physically fit of campers to do the dirty work for him by testing them out by winning six sports in a row that each of them competed in. Unfortunately for the campers who won the sports and earned the Camp Jellyjam coins they won for each sport, King Jellyjam seemed to get dirty, sweaty, and smelly just as quickly as anyone can clean him. Because of this, King Jellyjam had them scrub him and hose him day-in and day-out. And if anyone stopped cleaning him, even for a brief moment, King Jellyjam would gobble them up then and there, at least three kids sadly falling victim to this. A little girl named Alicia realized what was happening and tried to warn everyone else at the camp, but the counselors caught her and she was forced to wash the evil purple blob too.
This went on for quite a while, until one night, a girl named Wendy sneaked in and found out what was really going, unbeknownst to King Jellyjam. And the next morning, she returned with her brother, Elliot (whom she stopped winning a race) and yelled at the kids washing King Jellyjam to stop and lay flat on the floor. The kids did so, outraging King Jellyjam and he was about to eat Alicia but was unable to pick her up, due to his hands being too fat and clumsy to pick her and any of the other kids up. He then tried to wash himself, only to have the same result. King Jellyjam noticed Wendy and realized what had happened and was about to grab Wendy, but ended up suffocating in his own foul smell before he could do any harm to her.

King Jellyjam is a huge glob of purple, with enormous watery yellow eyes, a fat-lipped, two-tongued mouth and wore a gold crown on his head.
King Jellyjam was a terrible and disgusting slob of a monster. And even he couldn't stand his own foul smell, which is why he forced the strongest campers to wash him frequently. He had no tolerance for anyone trying to rest for even a second and wouldn't hesitate to devour the poor kid if they did so, his way of forcing everyone else to keep working. In spite of how scary he was, King Jellyjam was a very weak monster, due to being unable to move properly in his huge size, his foul stench and his fat clumsy fingers, which have been his biggest weaknesses.
