Wonda-chan appears as a rounded, chibi-style mascot figure standing in a gentle, welcoming pose. Her proportions emphasize a large head and compact body, with smooth sculpted curves and oversized eyes that carry a glossy paint finish. She wears a pristine nurse dress rendered in soft white and pastel pink, with a small red cross emblem on the chest and a matching nurse cap perched at a jaunty angle. Subtle fabric-like textures are suggested around the dress hem and sleeves, while molded details include a tiny stethoscope draped around her neck and miniature shoe details. The paintwork mixes matte and glossy finishes to highlight facial features and accessories, and she stands on a simple circular base that keeps the figure stable while displaying the mascot's approachable charm.

Wonda-chan is designed as a tiny ambassador of comfort and cheer, imagined as a perpetually upbeat mascot whose core trait is a caring, helpful nature. In the Nurse Dress Ver. she embodies the nurturing side of that personality: always ready to soothe, check on friends, and lend an encouraging smile. Collectors can envision her patrolling a miniature clinic in playful dioramas, offering bandaged plush companions a gentle pat, or simply brightening a shelf with her calm presence. This variant invites fans to explore scenarios of empathy and companionship, making her a popular pick for those who enjoy narrative display and soft character interactions. As a non-speaking mascot, much of Wonda-chan's appeal comes from her expressive sculpt and pose, which convey warmth and dependability without words. Owning this figure encourages imaginative play and creates opportunities to pair her with other characters for caregiving-themed arrangements.
