Jump into the Gumball Class Spirits game online straight from your browser or mobile without dropping a dime. So here's the deal: when Penny started kicking it with Leslie, Gumball went full-on jelly mode. Now his green-eyed monster is on the rampage. You gotta use some magic dust to nab Jealousy before it wrecks the whole school. Step in and help Gumball wrangle those evil ghosts in Class Spirits. The game's based on the episode "The Flower," but with some epic twists to keep the gameplay interesting. Leslie chillin' with Penny made Gumball lose it. His jealousy turned into a nasty spirit, trying to possess folks and spill their secret wishes, making them play dirty to get what they want. Gumball, with his trusty salt jug (because salt's like ghost kryptonite), has to lay down salt lines to trap the spirit and stop its chaos from spreading.
