The Rumbling Grotto is the twenty-first level in Pikmin 2's 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.

Sublevel 1[edit]

* There must be a grand total of 12 enemies, between the types marked with the asterisk. At least 3 enemies of each type must exist. The treasures match the carriers.

Note: The previous object numbers were gathered from a very basic reading of the game's files. Research is currently underway to get more accurate numbers.

The cave starts rumbling while Creeping Chrysanthemums, Cloaking Burrow-nits, Sheargrubs and Shearwigs come out of the ground. To avoid 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 sprays 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.
