Stu, Chazz & Howard take the Rugrats to the zoo, where the employees wear animal costumes.

So that Charlotte can conduct important business in peace, and so Drew & Stu can watch tennis, they tell Angelica that they'll buy a Cynthia Dream House and a mini sports car for her if she stays quiet. She ends up taking this ""quiet"" thing very seriously by not saying a peep, not even when the Rugrats pay a visit. Eventually, the Rugrats' racket ended up making her more angrier, with no way for her to vent her anger; also, her silence ended up affecting Charlotte's business deal, rather than helping it.

Susie was a first on her block to get a Cynthia Easy Cook Oven -- literally, as they weren't available to the general public yet; the makers were advertisers on the Dummi Bears show. The oven was so precious to Susie, she wouldn't sell it to anyone, not even Angelica. With the oven, she made some Reptar Snack Squares. The Rugrats ate them, but didn't like them. However, they lied to Susie and told her they were the best snacks they ever eaten; they lied (as recommended by Angelica, of

Rugrats play ""Follow The Leader"", with Dil being the leader. When Dil sucks his thumb (mimicking Stu when he sucks his own thumb after hitting his hammer on it), the Rugrats do the same, but fail to stop. When the adults noticed this, they panicked after reading in a Lipschitz book that thumb-sucking leads to poor academic skills and bucked teeth. Angelica uses this advice to get Chuckie to believe that they'll turn into ducks, when they get ""duck

At night, the Rugrats try to encourage Chuckie not to fall asleep, so he won't forget to wake up to go to the bathroom.
