Foamback Gnashlot

The Foamback Gnashlot is covered in a soapy substance that causes Pikmin that attempt to attack it from behind to start drowning, so Blue Pikmin are the recommended choice when fighting it; otherwise, Pikmin must be thrown at its face, which puts them at risk of being gobbled up in the beast's maw. The Foamback Gnashlot is blind, but will eagerly rush over to the nearest sound it hears. However, it isn't a very active creature and is generally found sleeping peacefully near water, making a surprise Pikmin ambush fairly easy so long as care is taken not to wake it up. Be aware that the beast will scatter bubbles that trap Pikmin inside when it shakes its attackers off, however.
