The nunchuck is very real, it just doesn't come with the bundle. Calm down you people and quit trolling him. Ask politely how he got it, for example, or just settle down with the fact that you DON'T have one and you never did get one in the bundle. Gold nunchucks aren't OFFICIAL, but they exist.
He very clearly stated "I got my Skyward Sword bundle, along with a golden nunchuck". He didn't say "I got my SS bundle which came with a golden nunchuck".
