It contains a monster within, and if enough time expires during the battle, the egg will hatch, revealing a random monster inside. Destroying the Mystery Egg before this happens will prevent hatching, but no EXP or gil will be awarded.
====Final Fantasy IV -Interlude-====
The only known monster that can hatch from the Mystery Egg is the Black Lizard.
====Final Fantasy IV: The After Years====
One hit will cause it to hatch, but hitting it hard enough to kill the enemy inside is the only way to allow killing bonuses and full Bestiary entries.
