A Mini Ship is an enemy in the Super Mario Land 2 Space Zone that resembles a small spaceship. The Mini Ship attempts to crash into Mario while in midair. To defeat this enemy, Mario must simply jump on top of the Mini-Ship.

In later levels, they gain an additional ability to inflate or deflate themselves. They can also become spiky and in this form, it is invincible. The safest way to pass them is to go through them while they are deflated.
