Louie makes a small appearance in "Goofy's Valentine Date". He also appears in "Pluto Saves the Day" just before "Goofy's Big Kitty" is shown, where Goofy tells him that this cartoon stars Goofy and him, then roars at him making Goofy say him and Goofy.
His appearance was modeled after the tiger in the Goofy short Tiger Trouble. The drawings of Louie in the model sheet seen below are animation drawings of the tiger from Tiger Trouble but without the stripes. Co-incidentally, Raja the Tiger, the secondary antagonist of the animated short Goliath II, bears a close physical resemblance to both Louie and the tiger from Tiger Trouble.
