The Purple Potty was built during the events of Captain Underpants and the Big Bad Battle of the Bionic Booger Boy - Part 2. It was invented by Melvin Sneedly so that George and Harold could retrieve the Combine-O-Tron 2000, which was previously destroyed by the ridiculous Robo-Boogers after it was used to separate them from him. George and Harold later used it to travel back in time and adopt Crackers the Quetzalcoatlus from the distant past, but when they attempted to use it the following day to return her to her proper home, it malfunctioned and sent them to a universe populated by alternate versions of themselves. The Purple Potty was destroyed when George and Harold attempted to use it to escape Tippy Tinkletrousers (who also possessed a time machine) after it fell from a tree. It was later replaced by the superior Robo-Squid suit, which does not require a day to cool off in-between uses.
