Lou Seal

Lou Seal is an official mascot of San Francisco Giants. He is a seal because of the San Francisco Seals, a former Pacfic Coast League Double-A (now Triple-A) team, one of the most sucessful minor league baseball teams. His name is a play on the word "Lucille" (however, officially he is a male and the person playing him is a man). He made his debut in 1996.
