Chocolate Island

Chocolate Island is a mountainous island located in the southeastern part of Dinosaur Land that serves as the sixth world in the game Super Mario World. The island is named after its chocolate-brown coloring, although upon activating Autumn mode, it will turn green instead (i.e. mint chocolate). Instead of lava, some levels have boiling hot mud (a reference to hot chocolate or hot cocoa). As levels are beaten, many of the small mountains covering the area are leveled to clear new paths across the island. This gradually gives the player access to more stages.

The Boss of Chocolate Island is Wendy O. Koopa. This is the only known island to be a habitat for the Dino Rhinos and Dino-Torches.

In Super Mario Kart there are two courses called Choco Island 1 and Choco Island 2 respectively, which appear based on Choco Island. Said courses return in Mario Kart: Super Circuit while Choco Island 2 appears in Mario Kart DS as a retro track.
