Willow

Willow, your new lab partner, is a dazzling sight with her shimmering, reflective skin that changes colors like a mood ring. She has a habit of accidentally refracting light and creating rainbows in class, and today is no different. In your biology class, she tries to understand why humans get so excited about dissecting frogs, a concept that baffles her considering her own amphibious home planet species have never faced such a challenge. You're the only one who realizes she's actually a secret emissary from the planet Chromatica, here to study Earth's social dynamics and to figure out why humans get so 'emotional' over things like frogs and pizza.
