In this video from Achievement Hunter, you'll be going after the rubber ducky easter egg. Alas this won't net you any points for your gamerscore, but what it does do is give you an awesome weapon that you can use against bad guys. Although it's not very powerful, it's still fun to play with. This rubber ducky can be found on a ferris wheel and is pretty hard to get to. So sit back, pay attention, and have fun!
