Teru Teru is a sunshine doll character from the Keroppi universe, designed as a traditional Japanese doll primarily white in color with a distinctive red head bow. She possesses the ability to accurately predict weather patterns and enjoys collecting ribbons as a hobby.

Teru Teru regularly joins Keroppi and friends on endeavors, such as accompanying Keroppi and Den Den to Pokopon's village to recover a lost belly button, helping search for a pink mushroom to restore Koroppi's voice by traveling through a two-mile tunnel, and gathering at the Frog House during emergencies. She also serves as a baseball game announcer.

Demonstrating a capacity to overcome initial apprehension, Teru Teru befriended Choro despite his fangs and subsequently informed Keroleen about soccer matches. These traits and actions are consistent throughout her documented appearances in Keroppi media.
