Minami Katayama features in the spin-off "Wake Up, Girl Zoo!" as one of seven animal mascots at a financially troubled Sendai zoo. She wears a tiger costume, consistent with her established animal motif from the main series and reflecting her original vibrant, energetic characterization.

Within the zoo's revitalization efforts, Minami participates in activities like advertising through leaflet distribution and engaging in pro-wrestling performances. However, the narrative focus shifts primarily to characters like Miyu and Nanami across the episodes, leaving Minami's individual actions and development largely unexplored.

Her established personality traits—a cheerful disposition and occasional nervousness—receive no expansion or new dimensions within the spin-off's comedic, episodic format. The shorts do not incorporate character-specific background stories, interpersonal dynamics, or personal growth arcs for Minami. Her role remains visually tied to the tiger imagery, maintaining this association without introducing unique narrative elements or development for this adaptation.

No additional official media expands upon her portrayal or evolution specifically within "Wake Up, Girl Zoo!".
