Puppy Shower Games/Gifts?

I recently discovered that my friend had bred my dog while I was away. I had an ultrasound appointment yesterday and they said there's 7 puppies, although she might miscarry one or two. So I'm deciding to have a puppy shower for my dog, I know it sounds crazy, but it'll be a lot of fun. And it'd help me out a little on cost, I mean 7 puppies!! What could I do for games? I'm having the party at my friends house, she's got a pool, huge deck and yard, and a hot tub. And for gifts, I wa thinking like maybe small bags of puppy food, toys, gift certificates to pet stores. Any ideas will be great, thank you.
