Swampdon are extremely territorial creatures, claiming entire shorelines as their nests; they will viciously attack anyone who enters their domain. Their tails are capable of smashing entire boulders, and their strong arms allow them to swiftly swim.

Any frontal attack is repulsed. If it senses the approach of a storm and a tidal wave, it protects its seaside nest by piling up boulders.
