Okay, so I don't know if this is a good idea or what you people will say, but I have a suggestion. I think that during months where CS was open last year, like April or July, there should be a dog that you can get only one of, and it has the chance of turning into any of the dogs from that month the previous year. Does that make sense? Here's an example:
During July 2009, there is a "mystery puppy" on the wolves/dogs page. When you adopt it, it can be a moondog/sundog/raccoon tail/etc. newborn from July 2008. But you can only get one of these dogs.
Good idea? Bad idea? Please post and tell me what you think.
