Battle Course 3 is an ice-themed battle course in Super Mario Kart. It has not returned as a retro battle stage yet.
The battle stage has similar features to the other battle courses in the game, having an open center and walls forming concentric squares with small breaks on each side of the square course to serve as passageways. It features several ice blocks which can be broken, as well. This battle course resembles Vanilla Lake.
Mario Kart Trivia
In the beta version, this battle course was initially going to take place on Choco Island instead of Vanilla Lake, but was changed in the final version.
