Megamouth Terratoad

The Megamouth Terratoad is the singular member of a separate subspecies of Amphituber found in Pikmin Z. Although a species of Amphituber, it drastically changed to a more terrestrial lifestyle as contrast to the typical Wollywog.

Biology
Mergamouth Terratoads aren't commonly found near water as opposed to a typical Wollywog, able to survive further inland with its drier, water-holding skin. It is an ambush predator, and hunts similar to a Emperor Bulblax: it buries itself in the dirt and waits for unsuspecting prey to venture close, to which it launches out and snatches it in its large maw.

Piklopedia entry
''To think that a humble Terratoad would evolve into a predator like this. It just proves though that any animal can take any advantage in terms of niches and evolution. Though, it still has some way to go until it can get some stronger limbs to move around.''

Strategy
You're unable to hurt a Megamouth Terratoad while it's underground, so to attack it you'll have to get it above ground. There's a number of ways to do this: Either luring an enemy into the radius of the predator, or simply walking closer to it and avoiding the pounce. After it launches out of the ground, it is left open to attack. However, it'll shake off Pikmin and attempt to crush them underneath it, so be wary of that during your approach.
