Cappuccinousa is a male rabbit from the magical realm of Bunniesfield. He is one of fourteen bunnies dispatched to the human world to fulfill tasks assigned by the Two Queens. Possessing tan fur and black eyes, he is the twin brother of Latteusa. Both twins specialize as baristas in coffee preparation. After arriving in the human world, Cappuccinousa and Latteusa befriend a human girl named Sophia and assist her culinary endeavors. Though initially concealed, their presence is accidentally revealed to the human town. Cappuccinousa eventually takes up residence with one of Sophia's friends, sharing this home with three other bunnies.

Cappuccinousa shares a distinctive ability with his twin: he can raise his ears vertically, often displaying this trait during intense focus or while busy with tasks. He enjoys reading during his downtime. Demonstrating dedication to his coffee-making craft, he contributes to community activities alongside the other Sugarbunnies. His name directly reflects his coffee specialization. Within the bunny group, he works cooperatively with Latteusa in their shared profession. His core attributes remain consistent across documented media.
