The Poptropica Blimp is a large yellow and gold-striped blimp used to navigate Poptropica. When you go into the blimp, you are brought to the map, where you can visit other islands. The blimp's most important roles are on Survival Island, where it gets destroyed during a storm, and Blimp Adventure, in which the blimp has a bucket hanging down from it that helps extinguish fires.
The blimp appears on the Main Street (or its equivalent) of every island except Galactic Hot Dogs Island and the episodic islands. It is also found on the surface of the moon on Lunar Colony Island, the rest stop on Mystery Train Island, and inside C.J.'s bedroom on Shrink Ray Island.
- Official merchandise of an inflatable toy blimp has been released.
- On Steamworks Island, there is a small model of a mechanical blimp in Sully's Steam-Powered Paraphernalia.
- Wimpy Wonderland Island has a paper-sketched Blimp instead of a colored one, which fits the rest of the islands theme.
- It is revealed in the Skullduggery Island book that the blimp's nickname is Aurora.
- In Back Lot Island, the blimp is referenced for the first time during the course of the island, being called a "golden blimp."
