Friends

 * Binky Barnes - Probably the weirdest and most unique friendship in the entire Arthur show. In the episode "Muffy's New Best Friend", it showed Jenna and Binky playing soccer together. The episode also showed Jenna and Binky having the same taste in movies.
 * Francine Frensky - Even though it seemed that Francine made Jenna feel guilty about the 'Athlete of the Year' award, in the end, Francine made up with Jenna. After that, Francine and Jenna became good friends. Francine was even able to pull some strings to get Muffy to invite Jenna to her sleepover. Francine is also the only friend who knows Jenna's real secret.
 * George Lundgren- In Buster Makes The Grade we see Jenna at the Sugar Bowl with George along with another unnamed rabbit. She also, at Muffy's sleepover, joked that she had a crush on George.
 * Buster Baxter- In Buster Makes The Grade Jenna invites Buster to have an ice cream with her.
 * Alex- Jenna is seen with Alex in some of the episodes like Buster Makes The Grade.
 * Maria- Jenna has been seen with Maria many times especially in class together.
 * 4th Grade Female Cat (Number 2)- Jenna is seen with her in the library while they are reading Henry Skreever book to each other and talking about it.

Trivia

 * Jenna hates Hockey.
 * Jenna suffers from Nocturnal enuresis, commonly known as bed-wetting, and often wears a diaper to bed, referred to as a "Pull-Up" (a take-off from Huggies Pull-Ups, but more based upon GoodNites to fit for her age).
 * Jenna is midfielder for the Lakewood Elementary Soccer Team.
 * She is lactose intolerant.
 * She spoke for the first time in the episode Buster Makes the Grade.
 * The last time she was heard speaking was the episode Binky Goes Nuts.

Later Seasons
In later seasons, Jenna has practically disappeared. While she is still frequently seen in the background, her talking roles have decreased significantly. Since "Binky Goes Nuts", she has not spoken at all. This might mean that Jenna won't have any speaking roles in later seasons.
