Battle Memory

The Firefly is an enemy in Mother 3. They are released in the Sunshine Forest by the Pigmask Army in Chapter 1. Contrary to what their name implies, these are regular flies that have been combined with a cheap lighter. Flint is the only one to encounter the Fireflies, fighting off a trio of them while trekking through the forest, which the Army set ablaze.

The Pyreflies of Fire Mountain are stronger version of the Fireflies.
