In Episode 2, she started chasing Spongy, Book, and Ice Cube, eventually sinking into Spongy. In episode 3 of BFDIA, Insectophobe's Nightmare 3, it is shown that Spongy throws up Evil Leafy. He was not possessed nor captured by Evil Leafy, however, Gelatin comes to freeze her with his syringe and writes "First!!" on her back, ending the episode. In episode 4 of BFDIA, "Zeeky Boogy Doog", Evil Leafy once again sinks into a character, only this time, it is Flower, who was frozen by Gelatin. In "Get in the Van", Flower spit up Evil Leafy. It is possible that she might've eaten Flower in Get in the Van. The episode ended when Evil Leafy ate the FreeSmart van along with Tennis Ball, Golf Ball, and Rocky starting the BFDIA 5b game.
