The Jeevils are the nemesis of the Gooys. They are wicked, and they’re only worried about Gems. They want them at all costs but, being cold and deceptive, they never lose their minds and are really focused when they meet a worthy opponent. They are masters when it comes to rotate rooms and areas to get an advantage, but they lack the brains to make a thoughtful use of powerups, like Gooys do. This doesn’t mean they are to be taken lightly.

Their appearance is similar to the Gooys’, but they look more fluid and less compact than their good cousins, and in fact often lose pieces and drops of jelly. They have two very bright eyes, without pupils, and spots on their back. Their usual colors are red, pink, brown, orange, scarlet, fuchsia… and all the variations of red.
