Where can you buy rare/weird musical instruments?

ooh... wth is tt >?

isit some kinda folk instrument ? ocarina ... something to do with harmonica ?
it's a wind instrument... right? haha. I've got a small one, bought it while I was living in Melbourne though. :)
I saw ocarinas for sale in New Zealand (south island, near a place called old macdonald's farm). :|

Sorry, that wasn't much help.
