Actually, i don't. Nobody has ever heard of Domo Kun in Holland.
A friend of a friend is coming over from Japan in november. I asked her to buy me a Domo Kun doll, but she didn't live in Tokyo and they were always sold out in her area.
I found a website in Singapore which sells some stuff, but if i order one more thing from the internet my girlfriend is going to kill me.
just in case though ... おもちゃ通販のトイザらス オンラインストア
I couldn't find domo kun but then again I'm really sure what his genre would be either. If I spend anymore time looking it's easier for me just to drive the block or 2 to toysrus.
