A young girl and her two friends from the exceptionally strange land of Oddsville make plans to celebrate Christmas together, but when she is late to pick them up from the train station, the pair wander out on their own leading to a delightful series of hilarious mishaps, inventions, and flights of fancy - until they find their little friend, who finally shows them the true meaning of Christmas.
Unfortunately the movie Tatu and Patu: An Oddsville Christmas is not yet available on HBO Max.
