Mr. Grimshaw now has rear legs and is working on the front ones. According to our worthy dime purchase of a used book, Frogs, once his front legs sprout he will cease eating (algae tablets, plants) and only use the food stored in his tail as his mouth will be changing and make it impossible for him to eat.
He is named after a trip to Vermont where our youngest, only five at the time, insisted we call him Mr. Grimshaw for most of the trip and also on calling me "Mean Judy". I am not named Judy and I don't think I am mean, but I think that was besides the point. Not sure what the point was actually.
