Pengoon

A Pengoon is an enemy in Wario Land: Shake It!. Its name is a portmanteau of "penguin" and "goon". It is a penguin that hides in "secret" places in icy levels. It can pop out their places to throw pebbles of ice at Wario. Pengoons only appear in two levels: Slipshod Slopes and Freezing Fields.

There are also two varieties of Pengoon: blue and pink ones. Blue ones are the most common and spit only one ice chunk when they spot Wario. Pink ones, which are less common, spit three ice chunks when they spot Wario.

Trivia

 * Although their artwork shows them holding an ice chunk, they never throw one in-game and instead, spit them from their mouths.
