Combat:
Shuriken are only dangerous in windstorms.  They use their echolocation to zero in on a target and angle their glide path to hit the target.  Once the target is hit, the shuriken lands and scuttles forward to finish it off with its whip-like legs.  If the target shows too much life, the shuriken will take to the wind for another pass or leave.
