Mini Egg is a move of Yoshi Kid in Paper Mario: The Thousand-Year Door. When used, Yoshi can make up to three eggs to throw at the enemy. When it hits it will cause damage and reduce the enemy(s) attack power and shrink them.
Press the A button when a star appears on the gauge.
Egg Toss (like Shrink Stomp) will not work on certain enemies and bosses.
