|Previous level||(1-) Leafpile Castle|
|Next level||(2-2) Pipebreak Cave|
Crystalswoop Grotto (or World 2-1) is the first level of Crystal Sewers in Newer Super Mario Bros. DS. It's an underground level serving as an introduction to the Hammer Suit.
Crystalswoop Grotto is unlocked by completing Leafpile Castle in Goldleaf Plains. Completing it will unlock Pipebreak Cave.
- Star Coin 1: Near the start, strategically jump off of a Swoop to get to a red Warp Pipe above. This'll lead you to a room filled with Swoops, and the Star Coin will be at the end of this room. It's recommended to use the Hammer Suit, as you can either roll along the floor, killing the Swoops you touch, or kill the Swoops with Hammers.
- Star Coin 2: Once you reach the second Question Block containing a Hammer Suit, grab a Buzzy Beetle and carefully dodge the Piranha Plants. Then, throw the Buzzy Beetle at the Star Coin below.
- Star Coin 3: After the checkpoint, go into the only green Warp Pipe without an arrow on it. It'll reveal itself to be a Pipe Cannon, and will launch you to the third Star Coin and to the top of the Goal Pole.
