New Super Mario Bros. X/World 2-1

World 2-1 is the first level of World 2 in New Super Mario Bros. X. It is a sandy level filled with many moving Brick Block platforms and grounded Piranha Plants, and Shy Guys. This level is also the first appearance of the Gold Flower and Boomerang Suit.
==Layout==
First, Mario will come across some tilting Brick Blocks, one of them is a ? Block containing a Fire Flower, and a Boomerang Suit followed by a Piranha Plant. Throughout the level, there are tilting Brick Blocks which acts as platforms, and Piranha Plants being the main enemies. There is also a Red Ring which will make eight Red Coins parachute into the level. After the checkpoint, there are also Note Blocks, Koopa Troopas and Koopa Paratroopas. After the last Piranha Plant, several tilting Brick Block platforms can help Mario reach the top of the flagpole.
==Star Coins==
The three Star Coins in this level are located very close to each other.
*Star Coin 1: Before the checkpoint, there is a gap on the ceiling. Attempting to pass through the gap will make a hidden block containing a coin appear. Mario needs to go to the left of the gap and jump towards the right at the topmost point. He should land on a platform. The Star Coin should be in sight now
*Star Coin 2: After the checkpoint, there is a yellow Warp Pipe. Warping through will take the player underground. The player can find a Gold Flower in a lone ? Block, which allows Mario to shoot fireballs that change Brick Blocks into coins, activate them, or score coins instead of points when killing enemies. When Mario sees the first Goomba, he should stop shooting fireballs (just in case). Mario can then use the Brick Blocks as platforms to reach a ledge where the Star Coin is. He can obtain it by shooting the obstructing Brick Blocks with fireballs. In any case the Brick Blocks were changed into coins, the player can still use the Goomba Tower nearby (if still intact) to leap up to the ledge.
*Star Coin 3: This Star Coin is located just before the last set of Note Blocks. (If the player just obtained the second Star Coin, he needs to go towards the left.) The player needs to use the Note Block to reach a high tilting Brick Blocks while avoiding the Paratroopas to obtain the last Star Coin.
