Aunt Miriam and Lou were not nice to each other. They always did and acted like Angelica and Tommy are today. Tommy and Chuckie go in the bathroom and find a hair dryer, a radio and a wig. They think Aunt Mirian is an alien and investigate.

The babies, Angelica, and Grandpa have a campout outside. Grandpa tells the legend of the Satchmo, which leads to Chuckie using the restroom, and Tommy figuring out where Chuckie is. Angelica Scares them, Stu is scared to let them sleep outside because of a campout when he was 34. He calms himself down and sleeps with the kids.

Intrigued by the neighborhood circus show, Angelica puts on a show of her own, with the Rugrats volunteering (actually, drafted).

Charlotte is having a baby, but Angelica does not like the idea of having another mouth to feed.

The Rugrats play-act their favorite super-heroes, ""The Mega Hyper-Heroes"", a Captain Planet-type program, as Angelica commandeers their action figures.

Stu invents a new toy: a scary walking, talking, heat-seeking clown doll. The babies encounter it, and are horrified. Eventually, it all comes down to a final battle royale between Tommy and friends and an army of ""Mr. Fiends."" The babies win the day...or do they?

Tired of being hassled all the time by her parents, especially when it comes down to the foods she's required to eat, Angelica doesn't take the law into her own hands -- she takes them to court.
