Stump Grotto

Stump Grotto is either the fifteenth or sixteenth cave in Pikmin: The War of the Pikmin Planet. It is located in the roots of an old tree at Waterfall Lake.

Enemies

 * Toady Bloyster

There are a few puddles of water here, one of which houses a Toady Bloyster. Kill it to get the key.

Enemies

 * Blue Bulborb x3
 * Water Dumple x5
 * Hermit Crawmad x4

A small sea covers this sublevel. There are a few large tree stumps around, however. One of the Blue Bulborbs has the key.

Enemies

 * Wollywog x3
 * Goolarva

This sublevel is very dark and hard to see. It is also small, so it is easy to get caught off guard. The Goolarva holds the key.

Enemies

 * Puffstool

This sublevel is dimly lit with glowcaps. A new enemy, the Puffstool, is in the middle of the area. Puffstools can spore Pikmin, turning them into Mushroom Pikmin and making them fight you. The overgrown fungus holds the key.

Enemies

 * Burrowing Snagret
 * Sheartwig x3

An old foe, the Burrowing Snagret, lurks somewhere on this sublevel. New enemies, Sheartwigs, can also be found here. Sheartwigs have more health than Shearwigs but are slower.

Enemies

 * Orange Bulborb x3
 * Dwarf Orange Bulborb x6
 * Volatile Dweevil x10

Many orange menaces are located in this sublevel, and you can lose a lot of Pikmin if you're not careful. Watch out for bomb-rocks that fall from the sky.

Sublevel 7
Thankfully for you, there are 2 Queen Candypop Buds here for you to use, as well as eggs. Prepare for the boss of this cave.

Enemies

 * Pileated Snagret

This is probably the hardest boss you've faced so far. Keep your Pikmin away from the Snavian's large beak and pummel it when it gets stuck in the ground. Also, there are a few bomb-rocks around, so try to throw them at it with Orange Pikmin. Once the annoying hybrid is defeated, it drops half of a valve. The other half is in the Maroon Maze. If you have both, you can enter the Rusty Pipeworks.
