Louie is a minor character in Oswald.
Louie acts similarly to his cousin. In "Odd One Out," Louie and Henry reunite and spend the day bonding with each other. Unfortunately, this leads to Oswald believing that Henry has forgotten about him. In "Goodbye Best Friend," Louie asks Henry to come with him to the Arctic, against the wishes of Oswald and the townspeople. Henry eventually chooses not to join Louie, who is last seen on the bus to the Arctic. However, Louie makes a cameo appearance in "Sammy Starfish Live!" as an audience member. This conflicts with the events of his previous appearance, as Louie moved back to the Arctic and would not have been in Big City.
Louie is black and white. He has an orange beak and two eyes. His flippers are black, and his feet are orange. The only difference between him and his cousin is that Louie wears a red bowtie.
