The Okotan Jungle Beast lives in the jungles of Okoto.
It avoids predators by blending in to the jungle floor and leaves. Even though it eats mostly plants and insects, including Skull Spiders, most villagers who aren't Protectors fear it.
It uses its green spikes for protection and the grey spike on its back to sense what it can't see around it. It also really hates Shadow Traps.
