Other than Peetie, The Island of Misfit Mascots is the living-place of several other mascots, all of whom supposedly have a lesson to teach, and none of whom are actual real-life mascots. Some of them have only a few lines of dialogue, the rest do not have any dialogue at all, and their names are not mentioned.
