Emily, A blue cow from Waldo's magic book comes to visit the store while Waldo's house is being painted. But she is very clumsy so Jeff volunteers to be the boss of her, which isn't easy. Jodie is upset because Emily keeps knocking down her displays, Sam is upset because she keeps eating his donuts, and Muffy is upset because Jeff hasn't got time to play with her. So Mrs. Pennypacker tries to convince them that they should never look a gift-horse, or cow in the face.
