Rocket is an item that makes go fly up very fast for a longer while than a Jet Pack. Therefore it is the best and the rarest item in Doodle Jump. However, it can be more commonly found in the Space and Arcade themes. There is also a Submarine Rocket in the Underwater theme. It has the same effect as the Rocket in the Space theme.

The rocket is the largest item in the game (larger than the Propeller Hat or the Jet Pack) and is red and grey (in Space) or yellow (Underwater). While flying inside, the Doodler will appear to be sticking his head out of the window.
