they no longer make tamagotchi oceans, i bought mine from a seller on ebay. in fact, all of the cool ones are no longer made... but who knows, because the connection and plus have been released, maybe there will be all new ones coming out.
i have an american one and i read that if you don't give it snacks it'll make it to adulthood. i was going to try this method but it got toooo demanding! i also heard pausing it was bad and it'll die sooner. that's dumb because me and everyother kid who has one has to pause it at skool!
