My kids and I share the same game cart. My big question is if there's an easy way to pass items from one 'save file' to another. We can do objects by dropping them on the ground but it doesn't work for things like the shark. There doesn't seem to be a 'community' locker that we all share, or maybe I missed it. Is there another method? Can we mail each other? Come to think of it, I haven't even tried that.
