So I was lucky enough to win a Chilly Goat from the wheel today and since the step is Hatch a Chilly Goat I popped it on the nest, sped the hatching and voila on to the last step.
I find it pretty cool that even under the description of the feeding step it says that if you collect all 12 zodiac animals then something special might happen!!
I had a level 10 Chilly Goat that I fed to epic and then I fed my baby 15 times and just sped 10 gems to skip the rest of the step. The Aquarius is now on the nest!! Best of luck to everyone!
