Some of these pictures and descriptions may give away plot details that you might not want to know before watching the film.
Cheetah is the real hero in this episode of the Tarzan series when he rescues Tarzan and Jane from the sexy Leopard Woman and her leopard cult army who are trying to prevent the spread of European Colonial Imperialism in Africa by scaring and killing white explorers. It's hard to see the leopard cult as villians now, but this was made in 1946 so they're the bad guys.
Tarzan, Jane, Boy, and Cheetah go to the city to shop. Boy and Cheetah watch a snake charmer play his horn while a cobra raises out of a basket. The snake charmer closes the snake in the basket and leaves. Cheetah picks up the horn and plays it and the cobra starts to raise up, lifting the lid of the basket. Cheetah sees the snake and tries to shut the lid with his feet. Boy also sees the cobra trying to get out and rushes over to close the basket to protect Cheetah.
Cheetah's horn-playing and snake-charming becomes a comic motif in the movie. Cheetah takes the horn back to Tarzan's treehouse and plays it to a basket, but then we see inside the basket and it contains wriggling worms instead of a cobra. Boy laughs at him.
Later Cheetah is playing the horn in the jungle and we see a large python crawling down a branch towards him. When Cheetah sees the snake coming towards him he looks nervous then runs away screaming. Tarzan and Boy look over but don't see the snake, so they think that Cheetah is imagining things and they laugh at him again.
We see shots of a live cobra in a basket, then shots a fake cobra in the basket, then a live Burmese Python crawling down a branch in the scene with Cheetah.
