Tommy's First Birthday - S1-E2
Trivia: The VHS for Rugrats: A Baby's Gotta Do What A Baby's Gotta Do's front cover has a picture very similar to the picture Didi took of Angelica, Tommy and Chuckie. However, the VHS cover has Tommy wearing his normal clothes. The Tommy's First Birthday episode is not included in the VHS and the background is completely different.
Answer: He doesn't at first because she already has a Cynthia doll of her own. But later when the doll goes missing she gets the new Queen of the World doll. But Spike ends up digging up her which she had buried and gives it back to her so Drew just decides to take the doll back to the store because she had her doll back.
Why can't Drew just let her keep it instead of returning it, even though she wanted it so much like she said to him earlier, so she can have them both?
