Pyoro is a secret minigame in WarioWare, Inc.: Mega Microgame$!, unlocked once all microgames are encountered and unlocked for free play. It also appears in WarioWare Gold in the game's Toy Room. In it, the player controls Pyoro, a small, red, bird creature, while several vegetables fall from the sky. The goal is to eat as many of the vegetables as possible by grabbing them with Pyoro's extremely long tongue, which launches diagonally when pressing . The player gets more points by eating vegetables that are higher on the screen and fewer for those that are closer to the ground. If a vegetable hits the ground before being eaten, it destroys the square of floor that it landed on, giving Pyoro less room to move around. If Pyoro himself is hit by a falling vegetable, the game ends. When Pyoro eats a white vegetable, a Tenshi appears and returns one lost square of floor.
