Cookie and Mojo have had innumerable adventures now with Sonic and his cohorts. They are quite the experts at running, jumping, grinding, and light-dashing through some wild arrays of traps, monsters, and "crazy gadgets" (as Cookie just described them). Thanks to Santa Claus (all you people), they have a tall stack of game disks -- many of them Sonic. Alane has now taken to warning them about playing too much, specifically the danger of not getting enough exercise.
In response I heard one them say yesterday: "But it's good finger exercise."
Ah, I see these games have not only developed their eye/hand coordination but also their negotiation skills (though perhaps those didn't need any further honing).
