Arthur's Tooth & D.W. Gets Lost

Arthur's Tooth: Arthur has a loose tooth, but he is the only one in his class that has not lost any of his baby teeth yet. He unsuccessfully tries various ways to get it out so that Francine would stop calling him a baby. Francine, later, unintentionally knocks Arthur's tooth out.
D.W. Gets Lost: D.W. wants earrings because her friend, Emily, has earrings. She asks her mom and dad, but they claim her ears will turn green. After D.W.'s persistence, Mrs. Read takes D.W. shopping for earrings only if she approves of them. While at the superstore, D.W. wanders off when her mom is distracted. Lost, she runs into Emily, whose ears have turned green. Emily directs D.W. back to her mom, who has not noticed that she left. D.W. no longer wants earrings.
