Birthday Island is one of the three islands on the Happy Archipelago and is the second largest of the three. Like its companion islands, this one is themed.

The island is under the surpervision of Honest John and Napoleon Léon of the Party Party Pirates, which also falls under the control of the Shahanshah Hearty Harold.
