Mr. Pepperpot is the husband of the main character in the anime adaptation of Alf Prøysen's stories. He lives with his wife in a small village and works as a painter and decorator. His personality is stubborn and hotheaded, particularly during his initial unawareness of his wife's recurring condition of shrinking to miniature size. For a significant portion of the series, he remains oblivious to her secret, which she actively keeps hidden from all adults. This lack of knowledge shapes his early interactions and responses within their domestic life.

His relationship with his wife forms a central aspect of his character. He is dismissive of some of her desires, such as deeming her wish for a mistletoe wreath for a Christmas kiss "unnecessary" and "silly." However, beneath this gruff exterior, he demonstrates care for her well-being, expressing concern about her potential disappearance during an outing. When he eventually discovers her secret later in the series, this knowledge shifts their dynamic. The revelation positions him as the sole adult privy to her condition, which he views as a potential source of personal embarrassment.

He functions primarily within the context of his marriage and household responsibilities. His role often involves providing motivation for his wife's actions or setting up scenarios where her shrinking occurs. Their marriage, despite minor frictions stemming from his temperament and initial ignorance, is fundamentally stable and affectionate. He participates in seasonal traditions like Christmas shopping, where his wife's interventions ensure he purchases specific items like a bird sheaf or mistletoe wreath against his initial objections.
