Ocean Sunfish come to the Sea in the summer. And, its not a big problem, but the true name is actually Animal Crossing City Folk, not Animal Crossing Lets go To the City.

I am sorry but I do not thing it is going to come out on DS. What I do know, though, is that there is an animal crossing wild world that is out now. I hope I have helped....
