Hobbes finds amusement in poking here and there in the pond, hoping to make a hidden frog plop into the cold water with a little "eep!". I don't think he sees them half the time as I found him poking a rock gingerly the other day thinking it was a frog.
The frogs have wizened up now and they just jump in when they see him coming. And instead of being disappointed, homeboy just plays it off by taking a little drink instead.
He is one cool cat.
