All will hatch in a max of four days. Any add ons will be randomized.

They will/can grow into something like this : and then an older form and finally the adult form.

Species sheet:

Squees are a CLOSED species. Group

You do not have to grow your squee up all the way if you do not want to. 

A squee is a 3 formed creature. The creature will always grow out of his/her puff ball stage (which is above) into its second form. The second form is able to eat, travel and live alone. Once they have reached the final stage of their evolution they are a predator and can eat large mammals. Depending on the Squee they don't have to evolve to the highest form if they do not wish to. The Puff ball is about the size of a hand. Once this stage has passed it grows to the size of a medium dog. Once in the final stage they grow to the size of a lion. Their body in the final stage is lion like. They usually live in groups and can come in any color. In the Puff ball stage markings are not fully developed but will become more defined when in the second stage.

Just some general info. When bought you will get the second form. Depending on your wants you can leave it in the second form or grow it to the 3rd form after a week of owning them.
