Japanese weirdness - Making an ocarina out of a carrot

Have you ever seen someone make an instrument out of a fruit or vegetable? NO? REALLY? Okay, me neither, until now.
People who are familiar with the Legend Of Zelda-series may know of this instrument called Ocarina (otherwise, here is a picture for you:)

I just found a video of a Japanese dude making one of these out of a carrot! And on top of that, you can really play music with it! I saw that he has also made ocarinas out of different kinds of fruits and vegetables - how do you come up with stuff like these anyway?!

It's just weird. But cool.
