Who is the jazz-loving, trumpet-playing alligator in the Disney film 'The Princess and the Frog'?

The Princess and the Frog is a 2009 American animated musical romantic fantasy comedy-drama film produced by Walt Disney Animation Studios and released by Walt Disney Pictures. The 49th Disney animated feature film, the film is loosely based on the novel The Frog Princess by E. D. Baker, which is in turn based on the Brothers Grimm fairy tale "The Frog Prince". Written and directed by Ron Clements and John Musker, the film features an ensemble voice cast that stars Anika Noni Rose, Bruno Campos, Keith David, Michael-Leon Wooley, Jennifer Cody, and Jim Cummings, with Peter Bartlett, Jenifer Lewis, Oprah Winfrey, Terrence Howard, and John Goodman. Set in 1920s New Orleans, Louisiana, the film tells the story of a hardworking waitress named Tiana who dreams of owning her own restaurant. After kissing a prince who has been turned into a frog by an evil witch doctor, Tiana becomes a frog herself and must find a way to turn back into a human before it is too late.

Michael-Leon Wooley does the voice of Louis, a friendly, neurotic, trumpet-playing alligator whose dream is to become human so he can join a jazz band. His name comes from the famous jazz artist and trumpeter, Louis Armstrong.
