The akata can enter a state of hibernation for an indefinite period of time when food is scarce. When an akata wishes to enter hibernation, it seeks out a den and surrounds itself in a layer of fibrous material excreted from its mouth. These fibers quickly harden into a dense, almost metallic cocoon. While hibernating the akata doesn't require food or water. The cocoon has AC 18, 35 hp, and a damage threshold of 10. It is immune to fire and bludgeoning damage. As long as the cocoon remains intact, the akata within is unharmed. The akata remains in hibernation until a living creature comes within 10 feet of the cocoon, or it is exposed to extreme heat, at which point it claws its way to freedom in 1d4 minutes.
