you can enter pets and find pets. If you enter a pet, you get to also say what you want in return.
(ex: Person 1 enters an adult evil sandman. They say they want an ancient samoori that has spritely. Player 2 goes to find an evil sandman. They have the samoori that person 1 wants. The hatcher automatically hatches the two pets.)
Even if Player one is offline, it hatches. If so, Player 1 will receive their egg when they log back on. If you put a very specific pet you want, such as a epic sea dragon with tower shield, spritely, and spell proof, it may take a very long time. You can withdraw your entry at any time, but can only have one entry at once.
