Wuhu Island

Wuhu Island is a fictional tropical island inhabited by Mii characters where some Wii, Nintendo 3DS, and Wii U games take place such as Super Smash Bros. for Wii U, Pilotwings Resort, and Wii Fit.
It first appeared in Wii Fit where it was known as "Wiifity Island", but was renamed two years later in Wii Sports Resort. The word "Wuhu" in the island's name is a pun on the interjection "woo-hoo".
Wuhu Island is known for its massive volcano Maka Wuhu (also known as the heart of the island) which hasn't erupted in over two hundred years. The volcano received its own track in Mario Kart 7 for the Nintendo 3DS.
==Trivia==
*The Red Iron Bridge that resides on the island is a reference to the Golden Gate Bridge in San Francisco, California.
*Wuhu Island is the longest course in Mario Kart history.
