Tropical Island

From the Super Mario Wiki

Tropical Island is the second floor in Mario vs. Donkey Kong 2: March of the Minis. The background includes palm trees, two overlapping islands, and a sun which resembles a Shine Sprite, but without eyes. The ground is beige with a purple lining along the top. The Mini-Marios and Mario had to pass through here on their quest to save Pauline from Donkey Kong.

This area introduces mini crabs as well as color switches. Color switch related puzzles are common among this world's levels.
