First appearing in Batman: The Animated Series, these two pets were loyal to the mad man, Joker, himself. In Mad Love, it is shown that the Joker abuses these hyenas, prompting Harley Quinn to take them in herself. He loves to laugh like a maniac and attack anyone Harley unleashes them on. His laugh is lower than his brother's, Bud.
