Kal is a student at South Park Elementary. She first appeared in the Season Eight episode, "Stupid Spoiled Whore Video Playset", as one of Wendy Testaburger's friends outside of Bebe Stevens' group. In the episode, she was seen playing with the eponymous playset.
Kal has wavy, shoulder-length dark brown hair, with a lock of it hanging down the center of her forehead; identical to Isla's. She wore a pink bow in her hair, an orange T-shirt with red trimming, and green pants. Kal was shown unclothed in "Stupid Spoiled Whore Video Playset", making her the second fourth grade girl to be shown unclothed, the first being Wendy Testaburger during her breast surgery in "Bebe's Boobs Destroy Society".
In "Stupid Spoiled Whore Video Playset", she is seen playing with the eponymous playset, along with Jessie. Due to the fact they were hanging out with each other outside of school, we can assume they are good friends.
In "Stupid Spoiled Whore Video Playset", Wendy seemed to treat Kal and Jessie as "back up" friends, only trying to hang out with them when her "clique" was acting strangely.
