Fireflies are creatures that can be recruited in Dungeon Keeper 2. Like their cousins from the first Dungeon Keeper, these creatures are excellent scouts, but are very fragile. With their own personal light-source, these creatures are adept at exploring all of the nooks and crannies that any expanding dungeon invariably uncovers. They are swift enough to avoid most trouble and can even fly over hostile terrain to get to those hard to reach places. Fireflies tend to avoid combat as much as possible, although they do make excellent early warning systems.
- Melee - Fireflies flail their legs to scratch at enemies.
- Whirlwind - Acquired at Level 8, Whirlwind allows a firefly to create a powerful wind to blow enemies away.
Fireflies have few needs other than a little lair-space, food and a regular wage.
Fireflies hold no enmities with other creatures and will not shirk responsibility. They are, however, very weak and ill-suited for combat.
