The Green Slime Egg is a rare item that allows players to hatch a Green Slime in a Slime Hutch. This creature can then produce resources such as Slime Balls, which are useful for crafting and trading. Obtaining the egg can be a challenge, as it requires either a lucky drop from slaying Green Slimes or using a Slime Egg-Press with 100 pieces of Slime. Once hatched, the Green Slime becomes a part of the player's farm ecosystem.
