Cookie Monster tries to feed his baby cousin lunch, but she rejects the cookie he tries to feed her. Ernie passes by after a visit to the grocery store, and points out that while both of them may look similar, they are also different. Cookie explains his problem, but finds that Cousin Monster enjoys carrots, apples, and celery. Ernie becomes discouraged since Cousin Monster has eaten all of his groceries, and is left with an empty paper bag. Cookie solves the problem: he eats the bag.
