Treasure button

A treasure button, also referred to as a Button, Ⓦ logo button, or Ⓦ Button, is an object found in Wario World. Ground-pounding, punching, or throwing an enemy at a treasure button makes a treasure chest containing one of the treasures appear on a panel of the same color somewhere else in the level.

In each level, there are eight differently colored buttons: red, yellow, chartreuse, green, cyan, blue, purple, and pink.

When Wario finds that treasure, the treasure spot and the button turn gray.
