Bud and Lou

Bud and Lou are happy to see their mistress.

Bud and Lou[1] were a pair of hyenas owned by the Joker and Harley Quinn. Harley was their primary caretaker, and she affectionately referred to them as her "babies."

Background information

Bud and Lou are named after comedy duo Bud Abbot and Lou Costello. The basic idea of Joker having hyenas as pets was later carried over to Krypto the Superdog, The Batman, and Batman: Arkham City.

According to the DVD commentary for Batman Beyond: Return of the Joker, the addition of the character Woof, a gene-spliced hybrid of man and hyena, as a member of the Jokerz gang was a direct homage to Bud and Lou.
