Pedos de colores

Rafi is a pig who is constantly ridiculed. When someone walks by, they call him a "pig" without any consideration. Does being a pig automatically make him a pig? He insists he's the cleanest in his building! However, the constant jeers leave him feeling discouraged. These thoughts lead Rafi to have a very strange dream, where the city sky is awash in every color imaginable. But what are all those clouds? And even stranger... what strange smells! In this dream, Rafi calls himself the Pig Detective! Will he manage to figure out what all those colorful clouds are?
