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.
- The title might be referred from the 1998 Powerpuff Girls series episode "The Powerpuff Girls' Best Rainy Day Adventure Ever".
- Robo-Blossom is an obvious parody of RoboCop.
- Oligopoly also an obvious parody of an famous board game Monopoly.
- When Cave Blossom cried "Blossom, smash!" might be a homage of Hulk's catchphrase "Hulk, smash!" from the Marvel franchise.
- The portal gun Buttercup uses is a possible reference to the Portal Video Game series.
- This episode shared the same title from the Clarence episode.
