Down South is an animated short film distributed by RKO Radio Pictures, and is the ninth of the twelve Toby the Pup cartoons.
As he has to shake hands with just about everyone who comes aboard, Toby struggles to keep a smile on his face.
When the boat finally leaves the harbor, the passengers are treated to some entertainment as Tessie sings the song "Mississippi Mud" at the center of the main deck.
The boat then approaches a waterfall but Toby is able to reach it and gets back on board in time.
As the boat reaches the edge of the waterfall, the paddle wheels at the front work like airplane propellers, enabling it to fly.
