In Egg Hunt 2013 there was an alien parasite, if it bit the player the player would die. After the player dies, the egg will start to emerge from his or her torso. Another player would simply have to touch the egg while it was on the torso, and the egg would burst. After it burst, they both were awarded with the Eggtraterrestrial.
This egg was impossible to obtain without a second player, so if you are hunting for the Eggtraterrestrial you must bring a friend!
- This egg was removed a few days after Egg Hunt 2013's release due to the entire egg being a reference to Alien.
