Pascoon expands and contracts its silky cocoon as it produces spores. The mushrooms on its back vent these spores into the air whenever it becomes full, blowing them into air currents to fly miles from their source.
Pascoon feeds by sucking sap from the trees within the grove it dens in. If the mushrooms on its back are in danger, it uses Harden to toughen itself up and take the hit in their place.
To avoid detection by its enemies, it hides motionlessly beneath large leaves and in the gaps of branches. A Pascoon has parasitic tochukaso mushrooms growing on its back.
