Amakagame

Description
Amakagame are bulbous creatures that live in the cave systems of the 3rd layer. They're essentially just a huge stomach. Their bodies are covered in veins which it uses to attach itself to the cave walls. Rather than actively hunting for its prey, its stomach acids smell strongly of Baracocha fruit, the Neritantan's favorite food. The smell wafts through a hole in the top of its bodiy and draws prey near before swallowing them whole. They have beady eyes and a puckered mouth, though it's not clear what their mouths are used for considering they don't eat with them. Their skin is very thin; Riko tore through it easily with a small dagger when she accidentally fell into one.

Its danger classification is unknown, but due to the fact that it's immobile as well as it being fairly easy to recognize when you're getting close to one, it can be estimated to be around ★ (Minor).
