The '''Rumbling Grotto''' is the twenty-first level in {{p2}}{{'s}} [[Challenge Mode (Pikmin 2)|Challenge Mode]]. As the name implies, it focuses on many ground-burrowing enemies, including an encounter with the [[Pileated Snagret]], making it a very challenging level overall.

The cave starts rumbling while [[Creeping Chrysanthemum]]s, [[Cloaking Burrow-nit]]s, [[Sheargrub]]s and [[Shearwig]]s come out of the ground. To avoid [[Pikmin family|Pikmin]] deaths, it is possible to reset the cave until the key lies right beside the player, which happens quite often.

More rumbling with the Pileated Snagret. Use all [[spray]]s here so the Pikmin don't get harmed, grab the key, and jump out.

If you are doing a 2-player Challenge, the battle can be very quick and easy. Stand on opposite side of the Snagret and have both players toss Pikmin rapidly at its head. If you do it right, it should always go back into the ground instead of eating any Pikmin, and you save time and deaths.
