In Pikmin: Connection of the Worlds

In Pikmin: The After Years
The Firewisp is an aggressive Honeywisp relative appearing in Pikmin: The After Years. Its insides are red and it carries a ball of fire on its base. When it is hit by a Pikmin, it drops its fireball, which explodes into a cloud of fire upon hitting a surface. This fiery explosion can not instantly kill Pikmin but does ignite them unless they happen to be Red Pikmin.
