Mini Ika Musume is captured in a charming chibi form that emphasizes her squid-inspired silhouette while keeping display-friendly proportions. The figure is sculpted in glossy PVC with a bright teal-blue hair color, and two long tentacle-like strands flow down from the top of the head to frame her face in a playful manner. She wears a simplified sea-blue swimsuit with small yellow accents, and her rounded fins and limbs are designed to look cute and approachable. The tiny pose captures her mischievous character—one arm raised as if to declare an invasion, a cheeky grin, and wide, expressive eyes. Subtle shading enhances the curves and creases, giving depth to the miniature without sacrificing its adorable charm. The figure sits securely on a small stand that remains unobtrusive, ensuring the focus remains on the character's expressive face and distinctive hairstyle.

Shinryaku! Ika Musume centers on a young squid girl who rises from the sea with a gleam of mischief in her eyes, determined to invade the human world. She quickly discovers that life above water is full of surprises, from blustery beachside crowds to busy seafood stalls and cheerful neighbors. Instead of conquest, she unintentionally forms friendships, learns human customs, and finds that cooperation and kindness can be just as satisfying as a successful invasion. Throughout the series, her enthusiastic but clumsy attempts to adapt create humorous misunderstandings, heartwarming moments, and a running joke about the unexpected ways humor and hospitality can bridge two very different worlds. The character’s tenacity, charm, and ever-present tentacles make her memorable and endearing to fans.
