In Pikmin Adventure (Neini version)
Shields are powerups appearing in Pikmin Adventure. They are blue spheres that protect Blue from damage by enveloping him in an energy bubble. The effects wear off after a short while. Shields can be found by plucking nectar weeds or by killing Energy Honeywisps.
