Bugrushes are very quick predators on their homeworld. While they normally will stalk prey at first, they will quickly rush at it when the opportunity arises to startle the creature. They use long spines on the sides of their bodies to make sure they don't tip over entirely and crash while chasing prey, in a similar manner to Trackrunners.
"Bugrushes are swift-moving, agile predators that hunt in the plains of their homeworld as the equivalent to cheetahs. They use spines to help steady themselves during their fast sprints."
