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. In Japanese-exclusive media, however, this jet has been mistakenly known as the Sky Pop II.

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.

Super Mario Maker
A Costume Mario costume based on the original sprite of Super Mario piloting the Sky Pop appears in Super Mario Maker. The costume was officially released on January 6, 2016, and can be unlocked by completing the Southwest Air Aventure Event Course. All of the costume's sound effects and fanfares (transformation, jumping, clearing a course, losing a life) are taken from Super Mario Land. Pressing up on the causes Mario's legs to appear from under the plane and face the screen, playing the sound for collecting a coin from Super Mario Land.
