Golden Egg Level 5

To get this golden egg, open up the credits screen (by pressing the i button on the title screen) and scroll to the very bottom or get 3 stars on all levels of episode 2 depending on the version (or scroll it upwards) until you see the egg. If the egg is tapped or clicked, it will open either Golden Egg Level 5 or the Mighty Eagle's Beak puzzle level, or mighty hoax 3 star
