About the pool. It looks like a blow up kiddy pool so I wouldn't think it has any added chlorine in it. Maybe it does. The only thing you can tell about it is that he probably purchesed the annie without thinking about its adult size(don't see how you would not know its adult size, its an annie for crying out loud). I know a guy that keeps a few annies from another site. They are so cool but seeing how big they will eventually get, Why would you buy one if you are worried about the kids? Stupid people
