Lorenzo is the titular protagonist of the 2004 animated short of the same name which was produced for the unfinished third Fantasia film.
Lorenzo is described as a cat who refuses to get away from his own tail inspired by tango during the development of the segment. Throughout the short, Lorenzo is shown to be selfish to four other alley cats outside the restaurant. However, as the cats scatter due to Molly arriving, Lorenzo feels interested upon her without a tail and in spite of his stubbornness, he has a good interest in tango.
Lorenzo is introduced as a cat eating cocktail shrimp at a restaurant looking at four cats sadly watching him. He refuses to give some shrimp to one of them, so he draws a sad face on the wall in pout and scowl. However, a sinister black cat named Molly arrives and Lorenzo notices that he has no tail so she becomes influenced into him. His tail suddenly dances with him in a tango uncontrollably, causing him to escape the restaurant and dance across the street.
While on a fountain, Lorenzo attempts to get rid of his tail, but the tail refuses to get off of its owner through many dangerous things that can be harmful to his tail such as a train, a power line, etc. When Lorenzo encounters Molly again with a knife, she gives him a negative influence towards him and his tail. Humiliated from all of this, Lorenzo sacrifices his own tail accepting the offer from Molly, causing his tail to be separated from him. Later, Molly, Lorenzo, and his own tail separated from Lorenzo himself dance together in a tango once again.
