Creative enough story, but I notice a crifical flaw: How the heck are goldfish supposed to interact? I find it impossible to visualize without coming up with some goofy big yellow object with dangling arms and legs, which means, well... there isn't really much room for customization in that area. Not that it is really defined as to what the said goldfish look like in the first place.

I just don't really see what would really lure me into it is my problem. Can't speak for other folks here.
