Wooden chest

A wooden chest is an object found in Wario World. They appear as wooden containers with a square-shaped base and are edged in dark metal rims, giving them a rustic look.

They can be forced open by any attack and reveal their contents upon doing so. As their wooden appearance compared to their metal counterparts indicates, rather than containing a treasure, wooden chests contain more common items like garlic, a bomb, or coins. When Wario re-enters a wooden or a steel trapdoor after having completed the sub-level inside, he finds a wooden chest with coins in it where the red diamond used to be.
