Rainwisp

The Rainwisp is a docile relative of the Honeywisp. Its insides and eyes are blue, and it carries a bead of water using the base of its body instead of a drop of nectar or an egg. Attacking a Rainwisp is pointless, as it would drop only the bead of water it was holding, risking the lives of non-Blue Pikmin it lands on or near as it splashes on the ground. It's possible that it is gathering water for its young to drink.

In Pikspore
PS undefined In Pikspore, these creatures are more aggressive, dropping its bead of water when Pikmin walk underneath. The raindrop quickly regenerates, making this an annoying foe when in groups.
