Hawaii

 is a group of tropical islands on Earth, and is one of the fifty states of the United States of America.

Hawaii was visited in The Adventures of Super Mario Bros. 3 episode "Reign Storm". Princess Toadstool needed a break from her duty in the Mushroom Kingdom, and was ordered to go on vacation by her doctor, along with Toad. While Princess Toadstool was in Hawaii, she met up with a surfer dude named Cutter, who quickly became her friend, and offered to give her surfing lessons. Along with surfing lessons, Princess Toadstool also went swimming, windsurfing, waterskiing and hangliding. While Princess Toadstool was away in Hawaii, Bowser and Kooky von Koopa tried to take over the Mushroom Kingdom by using a Robot Princess in her absence. However, Toad noticed Kooky spying on them from behind some bushes, and so he and Toadstool knew that something was up, and quickly returned home. Before she left, however, Princess Toadstool thanked Cutter for the wonderful time she had with him, and told him that one day she'd make him feel welcome in her world, although Cutter just thought she was crazy.

Hawaii, along with its capital Honolulu, also appeared in Mario is Missing! on the Globulator, the game's world map.

Hawaii is briefly mentioned in Dinosaur Dilemma. After Mario finds 300 Coins in an alcove, he exclaims that he has enough coins to "take a whole herd of cattle on a vacation to Hawaii".

In The Super Mario Bros. Super Show! episode, "Koopa Klaus", the Mario Bros. attempted to visit a land of Mushroom World named Hawaii Land, but Toad instead led them to the North Pole.
