Sherwin's Heart

Shirley ( Heart) is the main character, along with Sherwin and Jonathan from the animated short film 'In a Heartbeat'. First appears when it comes out of Sherwin's chest

Appearnce
Shirley is small, about the size of a hand, and bright pink. It does not have the shape of the organ, but the symbol that is commonly used in today's popular culture. Its eyes are large and with a simple black pupil, a typically cartoonish mouth, two commonly seen black eyebrows floating above its head, and two stick-black arms. Shirly seems immune to the effects of gravity and can float at will, but it also has a certain strength, greater than the one mentioned, since in one scene it is easily dragged.

Personality
Shirley seems energetic, well-intentioned, yet still determined, very stubborn and impulsive about their feelings. It materializes Sherwin's affection for Jonathan, even though he had no idea of such feelings, Shirley does its best in the film for Sherwin and Jonathan to interact.
