The doll in Prairie's room isn't just there for decoration or to attack just for fun. If you continually strike the doll with attacks, in time it will drop a "W Can." The "W Can" or Weapon Can refills all of the weapon energy for all of the Live Metals. The doll will only drop it if you don't already have one.
