Although Primesire tend to laze around and appear to lack energy, they become riled up over the simplest of things. Even a soft berry falling on them while they are lying around, even while awake, will drive them to a rage.

A Primesire hunts by leaving its mouth wide open in water and waiting for its prey to blunder in. When it becomes furious, its blood circulation becomes more robust, and its muscles are made stronger.
