1. The Powerpuff Girls meet the Powerpuff Girls Cathy Cavadini, Tara Strong & Elizabeth Daily as the original PPGs. Amanda Leighton, Kristen Li & Natalie Palamides as the reboot PPGs. They meet themselves by time travelling. Have Past Buttercup ask her future self about the future, then a flashback of Painbow shows twerking. When it ends, Reboot Buttercup shudders & says "You don't want to know."
