Rootvils are very large, herbivorous animals native to Gamila's Purple Forest. They feed primarily on Heartwood trees. They use their long proboscises to pull trees out of the ground, then suck the juices out. They also consume the roots of the plant (hence the name), as the roots aid in digestion. The two ear-like appendages on the creatures' heads have an unknown use. The top theory is that they help in communication, but some think they could help cool off the Rootvil, attract mates, or even create powerful winds to blow bugs away. Rootvils are commonly left alone by predators due to their size.
