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