Ghost (Wario Land: Super Mario Land 3)

Zenisukii (ゼニスキー) is a member of the Brown Sugar Pirates and is a giant ghost. Zenisukii appears in Wario Land: Super Mario Land 3 in Parsley Woods, serving as the penultimate boss in the games. Zenisukii can paralyze Wario and is immune to body slams, coins, and fire. Zenisukii also turns invisible and drops coins that transform into Yarikuri Obake to attack Wario. Wario defeats Zenisukii by tossing his Yarikuri Obake minions at him.

Trivia

 * Zenisukii's name is derived from kozeni (coins) and suki (like), literally meaning "to like coins."
