The Wolves appear in "Go With Me." The wolves live in a pack together that Finn and Marceline temporarily join so that the two would assist in "creating excitement" to make Princess Bubblegum go out to the movies with Finn. After that ultimately fails, the wolves return at the end when Finn and Marceline destroy the movie screen because they hate the movie. They appear to be led by a larger wolf that wears a necklace with an orange-colored jewel. This could possibly be the elder wolf or alpha of the pack.
In "The Monster," a pack of wolves adopt Lumpy Space Princess as one of their own, letting her live with them until she annoys them to the point where they choose to maul her until she runs away from them.
