Ellery (for Ellery Queen- because he notices everything) also entertains himself in other ways.

The other day we were passing a corner Christmas scene that a local non-profit puts on. It involves several tiers of a landscape complete with two trains, a town and tunnels.

Out of curiosity I pushed the button and Ellery stood up against the glass on his hind feet watching the trains chug their ways past.

As I said, he is fun.
