'''Fire Snake Cavern''', or '''Layer-Cake Desert-3''', is the third course of [[Layer-Cake Desert]] in ''[[New Super Mario Bros. U]]''. It is a dark cave featuring the first appearance of [[Glowing Baby Yoshi]]. The level is unlocked by completing [[Stone-Eye Zone]], and completion of this level unlocks [[Stoneslide Tower]].

==Layout==
The level begins above ground, where a [[? Block]] containing a power-up is found, as well as a [[Warp Pipe]] leading to a [[dark]] underground area. Metallic  platforms that have lanterns at both ends and tilt frequently are found, as well as a [[Fire Snake]]. A portion of ground with Warp Pipes containing [[Fire Piranha Plant]]s follows, with a ? Block containing a [[Glowing Baby Yoshi]]. Two [[Fire Bro]]s. are found among a group of metallic tilting platforms. The top left one has a [[Brick Block]] containing a [[1-Up Mushroom]]. A passage containing [[coin]]s is found behind the Fire Bro at the bottom. The [[Checkpoint Flag]] is then found. A Warp Pipe leading to an area with [[Piranha Plant]]s and coins is located beneath the Checkpoint Flag. In the center is a [[Hidden Block]] with a 1-Up Mushroom. Another ? Block containing a Glowing Baby Yoshi is found, along with more tilting platforms with a Fire Snake and a [[Koopa Troopa]] on them. A [[Red Ring]] is then found, along with two Fire Snakes. More tilting platforms are found, as well as two Fire Bros. A Warp Pipe leads above ground to an area with tilting platforms and the [[Goal Pole]].

The player can skip the underground sections by using the [[Flying Squirrel Mario|Flying Squirrel Suit]] to fly over the wall at the beginning of the level. In ''[[New Super Mario Bros. U Deluxe]]'', [[Peachette]] can be used as well.
