Rainy Day is the thirty-second episode of the 2016 Powerpuff Girls series. It aired on Cartoon Network on October 22, 2016.
The girls find trouble when they try to occupy themselves on a rainy day.
A thunderstorm keeps the girls indoors with nothing to do, until Bubbles and Buttercup get the idea to play in the Professor's lab despite being told not to and against Blossom's objections. When she tries to stop them, Buttercup accidentally pushes her into a Time Dasher machine that changes Blossom into forms of different eras. Bubbles and Buttercup scramble to fix the problem before the Professor finds out.
