Real or Robots/Special Delivery - S1-E9
Other mistake: Before Tommy and Chuckie climb up back on Stu's bed position, Stu's hair is orange, just like Chuckie's.
No Bones About It/Beach Blanket Babies - S2-E9
Continuity mistake: In "Beach Blanket Babies" after Tommy pours the sea monkeys into the cooler, you see Chuckie standing next to him with shoes and socks on. In the next shot, Chuckie is barefoot.
Continuity mistake: When Grandpa Lou tries hammering a Christmas decoration in the cabin, Spike barks and startles Lou, leaving a wound on his finger. In the next shot when Didi hollers for dinner, a bandage suddenly appears on it.
Bug Off/The Crawl Space - S9-E5
Continuity mistake: In Moving Away, Tommy tells the other Rugrats how they first met when Angelica lied about the nasty things they did. However in the Crawl Space, there is a flashback of Tommy, Chuckie, Phil and Lil playing in the playpen when they were younger. Chuckie is scared of the Jack-in-a-box in that flashback, so the Rugrats could not have met for the first time back then.
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?
