Carapace Catacomb (or World D-A) is the only alternate level of Crystal Caves in Newer Super Mario Bros. Wii. It takes place in an underground cavern full of Buzzy Beetles.

Carapace Catacomb is unlocked by completing the secret exit of Toxic Wigglershaft. Completing it will unlock Cawcaw Treeway in Pumpkin Boneyard and Crystal Music House.


Star Coins

  • Star Coin 1: In the second area, find an alcove under the first arrow sign to find a pipe. Once inside, ride the giant Buzzy Beetle to collect it.
  • Star Coin 2: Just before the first exit pipe, bounce off a nearby Koopa Troopa to reach the ledge above to reach it.
  • Star Coin 3: In the final area, look for a pipe on the right, then use the nearby platform to reach it. You'll find it inside in plain sight.
