Harlequinsanity

Harlequinsanity is an animated comedy-slapstick television series produced by Amblin Television and Warner Bros. Animation. the is the eleventh installment of the Batman animated series (and the second Batman cartoon to not feature Batman, the first was the 2000 animated webseries, Gotham Girls). The title is a portmanteau of the words "Harlequin" and "Insanity", because of Harley's harlequin costume and her twisted sense of humor. it follows Harley Quinn (depicted as a cartoon-styled teenager) in her villainous misadventures like bothering a random superhero (Flash, Green Lantern, Power Girl, ETC), trying to explode the Hall of Justice or robbing Fort Knox. However, there will be slapstick-themed episodes such as shooing a Gopher away from Poison Ivy's garden or going on a joyride on Robin's R-Cycle. An additional segment: Return of the Totally Insane-y (A remake of Animaniacs), which continues the hyperactive adventures of Yakko, Wakko and Dot, as well as other characters like Slappy Squirrel, Pinky and the Brain, and Minerva Mink.
