Grit Grotto

Grit Grotto should be the fourth cave you visit in Pikmin 3: the War of the Pikmin Planet. It is located at The Warfield.

Enemies

 * Stone Bulborb

A new species of Bulborb is found here- the Stone Bulborb. These Bulborbs are really durable, but their weight makes them really slow. They do not sleep, either. If you attack carefully, you shouldn't lose any Pikmin. Jump down the hole.

Enemies

 * Dwarf Stone Bulborb x4
 * Stone Bulborb

This floor is a set of ruins, with Bulborbs blocking some of the passages. At the end is a small shrine that a Stone Bulborb patrols. Instead of a hole, a set of stairs leads down to the next sublevel.

Enemies

 * Sandy Burrow-Nit x3

Sandy Burrow-Nits are almost the same as Cloaking Burrow-Nits, except they have amazing camoflauge. Three of them patrol in a circle around an obelisk. Once they are taken out, the obelisk starts to rumble, and then the entire Sublevel descends! It stops on Sublevel 4.

Sublevel 4
This is basically just a long hallway leading to a hole to the final sublevel.

Enemies

 * Burrowing Snagret

A familiar enemy that proves to be the hardest boss so far, the Burrowing Snagret. Half bird, half snake, and all mean, this beast can be defeated using Pikmin 1 and 2 tactics. Once it is defeated, it drops a...key? Turns out it unlocks Challenge Mode! Who new?
