Kylie owns her. Regarded as the youngest of all the Ham-Hams, Penelope is rarely seen without the cover of her yellow blanket (although a few seconds in the opening theme show her blanket coming off, revealing her brown fur). While she is friendly to everyone, she feels particularly attached to Pashmina. Due to her age, she is innocent and naive, and she gets into trouble more often than most of the other Ham-Hams.
In season two, she has shown some cross-species affection for Herbert the Pig, a boy named Ethan, and a rabbit at Ethan's school. Unlike the other Ham-Hams, and perhaps because of her young age, Penelope can't say anything more than 'Ookwee!' or 'Ookyoo!' ('Ukyu!' in the original version).
