Captain Skull
Captain Skull is an undead pirate that appears in Wario World. He is holding the last key and is the last boss before the final boss. Wario battled him on a ship. Being the second-to-last boss, he has quite dangerous attacks, but all can be handled and dodged with ease. To smack some sense into the cap'n, scramble from his attacks, the scurry over to the boss, slam him, and execute one of Wario's powerful moves. However, this water is dengerous to Wario, also, so be careful!
Once Captain Skull has been damaged enough, with only two health skulls left, scoot over to the other half of the ship, dodging his attacks. When he starts flinging cannonballs, grab one, Power Throw it his way, and leap over to the dazed boss. Do a Piledriver or Wild Swing-Ding to knock out another health skull. Repeat once more to make him as good as dead. Or deader, as the case is.
When Captain Skull is done for, Wario receives the fourth and final Giant Treasure Chest Key.
