Pinballer

The Pinballer is a blue machine in Mario Pinball Land that can transform a character into a ball form. The machine has two yellow halves of a sphere that squeeze a character into a ball. It also has a gray platform that can extend upwards to move the character. The Pinballer appears only in an opening cutscene, after the player starts the game, and after they lose a life.

After a Toad gets transformed into a ball and launched out of the Sky Cannon, Princess Peach gets transformed into a ball and enters the cannon as well, but she gets blasted to Bowser's castle by two Goombas. Mario then enters the machine in order to save the princess.
