So, Bear and Mouse just invented the greatest game of all time. You know how babies do that super-annoying "I'm going to throw my toys on the ground every five seconds and make you pick them up" thing? ALL THE TIME? Well, guess who loves to run around picking things up?
Toddlers! Mouse throws her teething ring on the floor every two seconds, and Bear runs to pick it up and give it back to her. It's a win-win situation!*
*If by "win" you mean put something that's been here in your mouth. Which, I confess, I let Mouse do. Don't even start with me.
