Crikey the Kraken is the final boss of Treaure Island. Defeat him to conquer the area and receive free and member Loot Chests.
When the player enters his area they must fight three small waves of ghost pirates. After defeating all of them, two large tentacles will appear and begin attacking. They will slam down on the player, stunning them. If you get to the side of the arena, he will drop a tentacle and slide it across half of the arena, destroying the quick build as it comes to the middle. If you are hit when it's sliding it's tentacle, you will be thrown to the center of the arena. when he is low on health his head will rise up from the middle pool. Then he will start to shoot ink balls from his eye, slowing you if you land in his area.
The quick builds in this battle include two spike platforms, and one heart stand. The heart stand is in the middle, and when built it will drop three hearts which refill your health. At the sides of the arena there are two spike platforms to use against him. these are used to stun Crikey's tentacles if he hits it with a solid smack.
