9. Lucky 7- Star Fox
You cant say that game developers arent creative. One of the more imaginative eggs of all time was tucked away in SNES classic Star Fox, and it came in the form of a secret level, hidden within route 3. You can find it on the asteroid level by locating a bird nesting in a rogue asteroid and letting it hit you. By doing so you're transported to another dimension where you're required to fight paper planes and one of the hardest bosses of the game, a giant floating slot machine. In a game with space wars and talking rabbits even that seemed a little odd.
