Chiffon, a Sanrio character from the Cinnamoroll universe, lives near Cafe Cinnamon as one of Cinnamoroll’s friends. This white puppy features fluffy, cake-like ears that define her charm and name, with media occasionally depicting her ears and tail in brown, orange, or pink.

Athletic and energetic, she embodies a tomboyish spirit and acts as her group’s mood-maker. Chiffon excels at inventing spontaneous games and sports but struggles with studying and staying still. Her dream of winning an Olympic gold medal drives her athletic pursuits. She shows sensitivity toward animals and protectiveness over friends, notably shielding Cinnamoroll during a cyberbullying incident on his social media.

As a core member of the idol group Cinnamoangels alongside Mocha and Azuki, she participates in performances and group activities. Some media hint at a romantic connection with Cinnamoroll, though unconfirmed by Sanrio. She also mentors others, teaching Berry to ice-skate in the "Let’s Roll, Cinnamoroll" episode "The Floating Skater."

In "Cinnamoroll: The Movie," she joins the adventure to a magical candy land to rescue Cafe Cinnamon’s owner, Anna, after antagonist Chowder’s spell transports them. Her athleticism proves vital as the group overcomes obstacles in this fantasy world. Standing about 21.5 cm tall like most peers, she shares their diminutive size, though media sometimes scales her larger.
