King Louie Louie is king that appeared in the "The Three Ducketeers" episode of Bert and Ernie's Great Adventures.

When King Louie Louie's queen won't let him back into the castle, Ernie, Bert and Rubber Duckie scheme to get him back inside with an apology cake.

His name is a reference to the American rock 'n' roll song "Louie Louie" by Richard Berry.
