Wuhu Loop (known as Wuhu Island Loop in Europe and Australia) is the first course of the Flower Cup in Mario Kart 7. This course is based off of Wuhu Island from other Nintendo games such as Wii Sports Resort. The course is one of two to be found on Wuhu Island. Unlike most other courses, this course, along with Maka Wuhu and Rainbow Road, is split into three sections making the racers only having to do one lap instead of the usual three laps. The theme of this course is a remix of the title theme of Wii Sports Resort and it's the same of Maka Wuhu.
Shortcuts: It is possible to cut through the large grassy areas at the beginning with Mushrooms. There are also two glitch shortcuts in the track -- the first one is by driving past the tree near the end of the second section and falling into the sea, causing Lakitu to put the player near the ramp in the third section; the second one is performed by driving into the sea after the second boost pad near the lighthouse, causing Lakitu to place the player in front of the finish line. In the Patch version 1.1, these two shortcut exploits that existed on this track were removed.
Too bad that it's just only one lap, I was hoping for two and it will make it better.
