Moose/Goose Egg

The Moose Egg, also known as the Goose Egg, is an object from the Reign of Giants DLC. Every once in awhile a Moose will wander off to lay one of the eggs. The eggs radiate electricity and can be struck with a Hammer 4 times to cause it to hatch. Each strike with the Hammer causes the player 10 damage. 5 Moslings will hatch from the egg and attack the player if they get too close.

Trivia

 * Like the Goose, the egg will randomly alternate between being called a "Moose Egg" and a "Goose Egg".
