In the western localization of the game, the Special World's levels are all named after 90's American surfer lingo, with the names being Gnarly, Tubular, Way Cool, Awesome, Groovy, Mondo, Outrageous, and Funky.

However in Japan the first two levels are named "Fun Course", third and fourth are named "Even the Mario Staff is Shocked Course", fifth and sixth are named "Specialists' Course", and seventh and eight are named "Championship Course". None of the shared names are even differentiated through numbers, like "Fun Course 1" or "Fun Course 2".
