Winkle

Winkles are a race of snail-like creatures that inhabit the reaches of Chucklehuck Woods and only appear in Mario and Luigi: Superstar Saga. They own a sports recreational center called Winkle Stadium, which is also located in Chucklehuck Woods, and invite Mario and Luigi to play a game of Chuckorock Bounce for 500 coins. This mini-game is mandatory, as the reward is a Winkle Card that allows Mario and Luigi to traverse towards a fallen piece of the Beanatar.
