- Engaging Supporting Cast: Characters like Brown, Butt Detective’s loyal assistant, and the various animal residents of the town provide a rich tapestry of personalities that contribute to the series’ charm and appeal.
- Cross-Media Success: The transition from books to anime, and subsequently to films, has allowed the franchise to engage with its audience across multiple platforms, creating a cohesive and immersive brand experience.
