Pet Effects and Floors!

Hello everyone! I have 2 new things to show you in this post! First, pet effects! I found out that if you get all the acievements on a pet game, you might just get a pet effect! For example, if you played disc toss and got all the achievements, then your dog might get an effect like, say, getting little golden bones to fly out of your head. I've tried all i can to get one, i played Ssssnake all day, but i still need the last achievement to get an effect. The second thing is that at the spooky party, i discovered that you can sink into the floor! I don't really know how this is done, but i have some hunches.
