Greg the Egg is a familiar in Fiend Folio, a mod for The Binding of Isaac.

Spawns a familiar that wanders randomly around the room and blocks enemy projectiles.

Upon clearing a room, the familiar has a 35% chance to spawn one of the following:
• 36.36% - coin.
• 13.64% - key.
• 22.72% - bomb.
• 9.09% - battery.
• 9.09% - pill.
• 9.09% - card.

After blocking a projectile, the egg has a chance to hatch and spawn a random item from the Baby Shop item pool, removing the familiar in the process.

The chance to hatch starts at 2% after having blocked 5 projectiles, and is multiplied for every next hit taken.

Hatching will create a puddle of white creep on the ground that has no effect.

Greg hatching for the first time on a save file will unlock Devilled Egg and immediately spawn the item as Greg's reward.
