Each animal arriving from the zoo as a possible pet fails to suit its prospective owner, until just the right one is found. Movable flaps reveal the contents of each package.
Follows the progress of a hungry little caterpillar as he eats his way through a varied and very large quantity of food until, full at last, he forms a cocoon around himself and goes to sleep. Die-cut pages illustrate what the caterpillar ate on successive days.
