Coffretchi, a female Tamagotchi character introduced in the anime’s second season, joins the main cast as a primary member of the Dream Town Tama-Friends. She hails from her family’s Coffret Salon, assisting her parents in offering transformative makeovers that alter both appearances and emotions through a signature technique called "Dream Makeup." Her expertise extends to collaborations with a TV station, where she applies her skills professionally.

Prone to chattering nonstop when engrossed in tasks, her personality reflects intense passion and focus. The name "Coffret" originates from the French term for a small box, adapted through Japanese loanword conventions.

Within related media, Coffretchi debuted as a raisable character in Japan’s Tamagotchi P’s release *Dream Coffret ver. Tama Deco Pierce*, alongside Startchi and Benitchi. This iteration showcased themed accessories, clothing, and wallpapers that deepened her integration into the franchise’s expanded universe.
