Jenny can come off conceited at times, but she's only hiding her insecurity about her height. It's tough to be one of the tallest of the Skelanimals 'cause she can't easily go where they can. She and Marcy are close friends. She lets Marcy climb up her neck and slide down. They can do that all day and not get bored. Sometimes you'll see Marcy clinging on top of Jenny's neck sleeping.
