Wham-Shell was the long-standing king of a kingdom deep in the oceans of Skylands that for a long time lived peacefully. That is, until his underwater utopia was invaded by a legion of oil-drilling trolls that scattered his people to the wind.
Armed with a powerful mace that had been handed down from one king to the next for generations, Wham-Shell defeated the greedy trolls and drove them away. Soon after, he joined the Skylanders to help defend against this type of atrocity ever happening again.
Part of the Skylanders Swap Force Light Core collection, Whamshell's attacks include Malacostracan Mace and Starfish Bullets.
