Springtrap Dumple

The Springtrap Dumple is a advanced species of Ichthyosa Grub-dog found in Pikmin Z. It's appearance holds a resemblance to a elongated Water Dumple, with a circular mouth which expands to swallow prey. It is a decent swimmer, but relatively slow on land.

Biology
This species is an ambush predator with a high accuracy rate. It lies low underground, commonly underneath pools and shallow water, waiting for prey to swim by when it launches itself upward to swallow whole. If found on land, the attack is a diagonal launch out of the ground, which then it'll quickly burrow back underground from where it launched and bury itself again.

Piklopedia entry
''This species of Dumple, I observed, has developed a subterranean hunting technique, which it will launch forward after prey. Hard to say as to how it can sense prey, but my guess is that the lips are highly sensitive to vibrations in water and on land, giving this otherwise blind creature a means to see the world around it.''

Strategy
Either in water, or on land, your main objective is to make it come out of hiding, and dodge the attack. Attack it while it returns to its previous burrow, though the method is more difficult when underwater since it can swim faster than it can crawl.
