The Gerbil Jogger 2000 was one of Professor Poopypants' (who later renamed himself Tippy Tinkletrousers) early inventions.
Appearance
The Gerbil Jogger 2000 has two red Ps together on a lightning bolt. It has a glass screen so the gerbil inside it can be seen. When Professor Poopypants used the Goosy-Grow 4000 to enlarge the jogger, it grew to the size of a large building.
Trivia
- In Captain Underpants: The First Epic Movie, Professor Pippy Pee Pee Poopypants/Tippy Tinkletrousers was supposed to be in a white and purple gerbil jogger. It was later replaced by The Turbo Toilet 2000.
