Planetary poker

Last night, I randomly missed Pluto. Remember Pluto? The cutest planet ever? In my sleepy state, I thought of a party where all the planets except Pluto were invited. They'd play poker (like the dogs in the popular paintings); a game I'm not familiar with but am guessing is one you wouldn't want to miss if all your friends were playing.

I couldn't fall asleep so a quick sketch was the next step. Obviously. Dear Pluto, your absence will always be felt.
