Trivia

 * Main article: Golden Egg Level 5
 * After v1.5 the puzzle got removed and it got replaced by the one that we know today (also in the old PC ports of Angry Birds, when it had Poached Eggs, Mighty Hoax, Danger Above and The Big Setup, the sprites for the puzzle where still in the files).
 * There is a similar way of obtaining a silver hidden loot crate in Bad Piggies, by going to the credits and tapping it. This is possibly a reference to obtaining this golden egg.
 * This would mark as Mighty Eagle’s First appearance.
