The mushroom on Parabarel's head thrives in damp conditions, so Parabarel build dams out of wood for its spores to grow on. The fungus quickly rots the wood, so Parabarel must constantly cut down trees to reinforce their dam before it bursts.

It makes its nest by damming streams with bark and mud. Parabarel are known to infest the roots of large trees en masse and drain nutrients.
