Waiting for its evolution, Sylpede curls itself into a near-impervious ball that can roll at 250 km/h. While curled, it passively feeds on positive emotions it can feel, which seems to make it evolve faster.
It is usually motionless, but when attacked, it rotates at high speed and then crashes into its opponent. It sends a soothing aura from its ribbonlike feelers to calm fights.
