For those who don'T know the concept of adoptable eggs, here it is(thanks to my friend  aim who started this^^):

1-You buy an egg.
2-You tell me if you have a gender you prefer it to be.
3-You tell me which kind of animal you prefer it to be.
4-The egg will hatch within a few days.
5-I'll send you the picture with reference colors.
6-You enjoy your new friend^^! By the way, you can really do whatever you wish with that egg after you get it!
