Super Mario 3D Land

Super Mario 3D Land is like a high-speed 3D collision between New Super Mario Bros. and Super Mario Galaxy, featuring a reference to The Legend of Zelda. It marks the return of the Super Leaf from Super Mario Bros. 3, but instead of turning Mario into Raccoon Mario it turns him into Tanooki Mario (minus the statue ability, or at least until you acquire the Statue Leaf which is available in the Special Worlds). There's also the White Tanooki suit which makes Mario invincible, seen after you fail a course several times, and the P-Wing (also from Super Mario Bros. 3) which sends you straight to the flagpole if you fail several more times. Oh, and you can accumulate 1,110 lives.

Got all that? Good.

Yoshi
The sound heard when Yoshi pops out of an egg or is mounted in Super Mario World and subsequent games. In pre-release trailers, this was one of the sounds heard when Mario jumped on a Note Block. The Note Block sounds were redone for the final game.

Yoshi doesn't appear in this game at all, but did appear in the previous 3D Mario game, which Super Mario 3D Land shares an engine and various assets with.
