King is one of two rulers of Jammbo, along with his wife, the Queen. He thoroughly enjoys being king and creating arbitrary laws or relishing in the things that he is able to get because of his power, like toys and items. He spends most his time on "King Business" (what this actually entails is up for debate), but prefers to play video games or entertain himself with the many toys within his Gift Vault. (voiced by Adam Longworth (UK), Hector Garay (Spain), Peter Odring (US), Insana Tino (US on Disney Junior)).
Though he speaks in a quite regal manner, the King is pretty simple. He can be quite child-like, and in fact often acts like a misbehaving child.
