How to acquire Mighty Eagle ?

I am at level 53 in Eggchanted Woods and received bonus 5 but cannot activate it without Mighty Eagle. I googled stuff and someone said to click the grey eye icon next to the pause icon. My game has no grey eye icon anywhere at all. I went past to Bonus 6 and was able to activate it but 5 just sits there. I sure could use the feathers though! Can anyone help? How does one acquire Great Eagle in AB2 ? Thanks. Dar Novak
