Melorina is a Sweetspet, a Jewelpet variant hailing from Sweetsland. She manifests as a female poodle crafted from melonpan, a Japanese sweet bun. Her design features light cream fur as a base, with ears and tail formed from light lime-colored melonpan. Light pink eyes and distinctive green melon-shaped earrings complete her look, along with a melonpan garland encircling her neck.

Her personality exhibits multiple facets. She often presents as cute and joyful among other Sweetspets, though she can be an airhead. At times, she displays a mean-spirited or self-centered demeanor, yet she also shows capacity for caring towards others.

Melorina's background is tied to Sweetsland. She debuted in episode 38a of *Jewelpet Sunshine*, appearing at a Christmas party. She later featured in episode 19 of *Jewelpet Kira☆Deco!*, offering sweets to stars. Her most significant role is in the film *Jewelpet the Movie: Sweets Dance Princess*, where she serves as a chef, aligning with her food-based motif.

Conceptually, she originates from Japanese confectionery. Her primary motif is the melonpan, reflected in her ears, tail, and neck garland. Secondary motifs include the melon earrings, reinforcing the melon theme. Within the franchise, she is noted as the second poodle character introduced, following Prase.
