Get ready for pajama-party-rama-madness, guest-starring Catwoman, Poison Ivy, Hope, Mercy, the Body Doubles and more. After bombing out with Two-Face, Harley decides to gather the bad girls of the DC Universe for a sleepover. (How else to show off her wild new digs?) But she ends up with more guests than she's got miniature pigs-in-blankets -- and if that weren't horrific enough, there's a conspiracy afoot.
