Little Lambkins
A mother puts her baby boy in an outdoor playpen, but he's more mature than she realizes, and quickly breaks out, and with the help of a raccoon and a squirrel, they are soon raiding the watermelon patch. Mother returns: turns out it's moving day, and the family is moving to the city.
