The Pet Egg is a members-only land pet. It was released on April 13, 2017, and it is sold throughout Jamaa (including in the Diamond Shop) as part of the Eggstravaganza event. This pet is temporary, as it hatches into another pet precisely 72 hours (3 days) later.
The egg is round and smooth with four primary styles: spiky, sparkly, shiny, or plain. The egg can be customized with a bright primary base color and a secondary color that is used for stripes, which can either be vertical, horizontal, curled or removed altogether. The egg can also have one of four shadings applied to it.
Egg rolls away, then jumps back to its original stance.
Egg has the same pose sitting as it does standing but stops doing its breathing motion.
Egg moves left and right.
Egg sits still but has Z's being released.
Egg bounces up and down.
Egg jumps up and flips in the air, then falls back down onto the ground.
The Pet Egg cannot go to the Pet Stop until it is fully hatched.
When the eggs were first released, there was a glitch that allowed Jammers to see the pet they would hatch into. However, this glitch has been patched.
When it is taken into water such as in Crystal Sands, it appears to be on a donut-shaped floatie.
The floatie's stripe color when on water appears to be the second color of the egg that is chosen.
When clicked while in water, the egg will do the normal rolling action but after the action is done it will no longer have a floatie. The egg will remain in the water without a floatie until the player moves a bit.
When placed in a den, they appear to sparkle.
When looked at in an inventory, there is no name or adoption certificate for the egg.
When asleep in a body of water, they bubble but do not have the ZZZ action.
Flying animals cannot have eggs as their pet, possibly because eggs cannot fly or as a measure against finding out the pet before it hatches. The same is true for water animals in ocean areas.
There is a glitch when viewing pet eggs on other Jammer's Player Cards: initially, the pet egg does not have an adoption certificate button, but if a regular pet is selected and then the pet egg is selected again, the adoption certificate button will appear.
On the second day, the egg appears to have a crack.
This seems to happen exactly 24 hours after the egg is adopted.
48 hours after the egg is adopted the egg has a bigger crack and its eyes are visible.
When in the My Pet Menu and the egg is clicked, if the player tries to click the Pet Stop button a message will appear saying, "Your egg has to hatch before it can go to the Pet Stop."
However, eggs can still access the Pet Wash.
There is a glitch where the egg still travels in a circle floatie while on land.
After the update on October 26, 2017, there was a glitch where players could tell if the Pet Egg they were buying would hatch into a Pet Crow or not. When adopting a new Pet Egg, it would appear to be floating above the grass when compared to the other eggs if it contained a Pet Crow. This floating also appeared in the Pets menu and could be seen when walking the egg.
