On our last trip to Hokkaido, we saw Marimokkori all over the place flashing his excited dolphin at us. And we know what excited dolphins like to do don't we? - jump through hoops.
When the Marimokkori was first conceived, it was considered vulgar and didn't do too well until celebrities like Amuro Namie mentioned it on TV a few times - Marimokkori became a boom overnight. Some more examples of the goods available in the vid below and at the official marimokkori online store.
And for those who like pulling on their dolphin but feel uncomfortable doing it in front of colleagues - get one of these and pull on his one instead.
Despite the fact that this character constantly has his dolphin standing on end, Marimokkori is actually popular with the kids and now seems to be accepted in Japanese society. Would you feel comfortable with your kids playing with Marimokkori's mokkori dolphin?
