Anna owns Cafe Terrace, distinguished by her pink or red hair, a signature pink dress, and purple shoes. Her life changes when a small white puppy falls from the sky into her cafe's delivery basket. She adopts the puppy, naming him Cinnamon for his cinnamon roll-shaped tail, and integrates him into her existing puppy family: Cappuccino, Espresso, Mocha, Chiffon, and Milk. Anna provides care and a home for all the puppies at her cafe.

Her peaceful existence is disrupted when Chowder, a magical creature who admires Anna and witnessed Cinnamon's arrival, grows suspicious of the new puppy. One of Chowder's protective spells misfires, magically transporting Anna and the puppies to an enigmatic candy-themed world. Within this strange realm, a sentient entity imprisons Anna in a castle, intending to marry her. She remains captive for the majority of the ensuing adventure, dependent on Cinnamon and his friends to orchestrate her rescue.
