Wherever Peter saw a narrow place he never could resist trying to get through it. He was a long, slim fellow, with a small, snake-like head. And he always knew that if he could squeeze his head through a crack he could get his body through it, too. It is not at all strange that Mrs. Rabbit and Mrs. Squirrel and Mrs. Woodchuck as well as a good many other people did not care to have their sons in Peter Mink's company.
