Mini-Mega Island is the second secret world in Newer Super Mario Bros. Wii. It takes place on a grassy island filled with larger and smaller variants of enemies.

As with every secret world, it does not have a boss.


Mini-Mega Island takes place on a small, green island which has multiple hills and trees scattered throughout. There are quite a lot of flowers and bushes, along with fences and mini-hills. Its main gimmick is its "big and small" theme, featuring larger versions of several enemies, such as the Mega Goomba and Mega Urchin, as well as smaller versions of several enemies, such as the Micro Muncher and Micro Cheep Cheep. Mini-Mega Island is heavily based on Tiny-Huge Island from Super Mario 64.

Mini-Mega Island can only be accessed through a secret exit from Pillar Pass in Rubble Ruins. Completion of Formidable Fortress grants access to Bubble Basin in Mushroom Peaks.
