1st - Water from AP
2nd - Black hatchling from AP
3rd - Mint caveborn
4th - Guardian from AP
I didn't know what did descriptions mean, so I prefered to choose an egg visually. I liked Guardian very much - It looked highly uncommon comparing to one-colored eggs, such as green, pink or magi.
I also picked dino, and liked the egg badly. It lookes really cool. But then it hatched, and I considered it to be really ugly, as well as the adult dino. Hmm, particularly, I think they're ugly for today. The only cool thing about them is their eggs...
