This is the first episode to show Cartman without his hat, making him the first out of four of the boys to have his hair shown. Kenny is the second one as he is later seen without his parka in South Park: Bigger, Longer & Uncut (1999) and Stan and Kyle are first shown without their hats in How to Eat with Your Butt (2001).
All of the third grade students, excluding Wendy Testaburger, are re-used and appear as kids in the Nebraska mall, waiting to see Mr. Hankey:
- Craig Tucker appears multiple times throughout the episode.
- A boy wearing an orange version of Craig's coat and hat can be seen during the rioting right as the Brimmy throws a lit Molotov cocktail at the Lollyland setup.
- Butters Stotch, Red, Annie Knitts, Kevin Stoley, DogPoo Petuski, and Token Black are also seen in the crowd.
- A color swap of Bebe Stevens with brown hair and a dark green jacket is seen as the kids are being hit by the tear gas.
- There is also a blonde-haired boy, similar to Clyde Donovan, seen in the crowd.
- The Boy with Blue Cap is seen several times, although sometimes he can be seen with an olive coat.
- A red-haired boy, similar to Butters Stotch, and a brown-haired boy, similar to Kevin Stoley, are shown at the mall crowd scene. There is also a boy with black hair that is shaped like Butters'.
- A boy that looks like Bill Allen but with reddish-brown hair is seen being hit by tear gas.
- A color swap of Stan Marsh wearing clothes similar in style to Craig's is seen.

The only members of the Cartman family not overweight are Liane Cartman and Cartman's cousin, Alexandra.
All the Cartmans talk the way Eric Cartman does (e.g. "authoritah", "myah" instead of "here") implying he inherited it from his family. Elvin Cartman sounds nearly exactly like Eric, only his voice is higher pitched and childish. Only the men in the family seem to have this vocal inflection.
The character "Craig" appears at the Mall in Nebraska
