Proper input rules:
H.hhhh: (Dot delimited) At least one leading digit, and at least 4 decimal digits.(good: "0.1230", bad: ".123")
H:M: (Colon delimited) At least one hour digit, and 1 or 2 minute digits. (good: "0:1", bad: ":1" or "0:123")

(Although bare integer-input would work for both format cases, there currently deemed improper formatted input.)

Firefly is a Curiosity which can be used in the Study Report to earn Learning Points. Can be found everywhere at Night. Fireflies can be equipped on a Fishing Pole to be used as Bait.

How to Acquire

You can catch a firefly by right-clicking them while they are flying around, just like Ladybugs. They appear in Grasslands, Forest Terrains, and most likely on Swamps. Only at Night.
