After being exposed to high amounts of mamono mana, these large slimy beasts can be quite dangerous to encounter. They primarily use their large heavy bodies and leave a slime-like substance wherever they go, which they can also spit out as a form of projectile. They're large enough to swallow a human whole, which just happens to be one of their preferred meals. Don't worry, they can be calmed or even tamed as they're creatures not monsters, despite kinda looking like one.
