He is very fond of his trumpet and his dream is to become a famous jazz singer and performing in front of a human audience without scaring anyone.

Louis first appears after both Tiana and Naveen are transformed into frogs and stranded in the Bayou. Tiana and Naveen had great fear of Louis at first but soon realize he has no appetite for them. Instead Louis wants to play his trumpet while Naveen plays his ukulele. Tiana then tells Louis her and Naveen must be moving on. Louis then ask why. Naveen explains that they are actually human and the spell was done by a voodoo witch doctor. Louis then tells the duo about Mama Odie the queen of the bayou.
