Summary
"Harley's entire cast of crazy characters comes together to celebrate the birthday of cyborg senior citizen Sy Borgman...but is there actually a bigger secret behind this gathering? And in "Harley Loves Joker" part nine, Harley's spent a fortune building out the Joker Gang's new hideout, and now they're gonna have to take drastic measures to pay the bill!"-- Provided by publisher.
