Spong/Trashotic is mischievous and chaotic. As a trash-themed ghost from the toxic family, it has an appetite for anything with a repulsive odor, such as sewage water or trashes from a garbage bin. Spong/Trashotic is full of mischief who enjoys releasing its smelly odor to stink up its surrounding. This includes not only people but also anything such as a bunch of flowers that are set on a stand outside a flower shop. But when it switched to booster mode, Trashotic became very hostile.
