Swooper Cellar (or World D-1) is the first level of Crystal Caves in Newer Super Mario Bros. Wii. It takes place in a purple cave full of Swoops.

Star Coins

  • Star Coin 1: When you see the first Swooper, use him to reach an alcove above. Perform some wall jumps to reach a red Warp Pipe. Once inside, perform some dangerous parkour to reach it.
  • Star Coin 2: After the Red Ring, use the POW Block to find the Star Coin.
  • Star Coin 3: You might want the propeller suit for this. Just before the flagpole, you'll find some tilting crystals. The last one is below the Star Coin. Wait for it to tilt up before grabbing it.
