Sky Pop

The Sky Pop is a yellow airplane that first appeared in Super Mario Land and appeared again in Mario & Wario.

Super Mario Land
The Sky Pop is used only in World 4-3 of the Chai Kingdom. It can fire missiles with unlimited ammunition. Mario uses it primarily to defeat Chickens, Biokinton, Roketons, and Tatanga. After defeating Tatanga, Mario flies off with Princess Daisy in a separate flying machine that is jet-powered and has extra room.

Mario & Wario
After clearing Level 10, the Sky Pop is used to intercept Wario and drop one of his enchanted Barrels on his head as punishment for the all of mischief he caused to the heroes. The Sky Pop is shown to have a conventional-type landing gear configuration but uses a monopod instead of a tail-wheel.

Yoshi's Woolly World
Yoshi has a transformation based on the Sky Pop in Yoshi's Woolly World, known as Sky Pop Yoshi. It controls similarly to the Sky Pop's appearance in Super Mario Land.
