Trapmaw

The Trapmaw is an elusive, tunnel-exclusive creature of Pikmin Eco. Despite being drastically different from most of its relative, it is a species of Grub-Dog. It is a highly bulbous creature with four stubby legs, and a mouth that makes up over half its body. As the name suggests, it is an ambush predator, and remains buried underground with its mouth wide open like a trap. If something is caught in the center of its mouth, it will shiver and then after a second clamp its mouth shut on anything that's still there. This can mean it can swallow small enemies too. However, some treasures are found with the Trapmaw underneath them, yet they don't trigger its clamping response. Thanks to this nature, it is the game's equivilent to the Pearly Clamclamp of Pikmin 1.
