Mrs. Calloway jumps on top of Rico and crushes him. He is seen with several teeth missing and his tongue stuck out. He also has blood on his face.
Mr. Wesley is kicked in the head by a horse and knocked unconscious. He is later seen, still unconscious, being abandoned in a train cart in the middle of nowhere.
One of the three henchmen of Slim is whacked in the face with a shovel and knocked out.
A man is strangled and his face turns red. He is later hit with a hot branding iron. He appears unharmed by any of this later.
A train rolls off the tracks and nearly hits a group of people.
A rabbit is injured mildly throughout the film as a sort of reoccurring slapstick humour; he is hit in the head by horseshoes, his ears are caught in a wagon wheel, his buttocks is bitten by a cow trying to take out pieces of hair from his tail, he is chased by a drooling coyote and he has a wooden stump replacing a missing limb, among other things.
Characters in mild peril (stuck in a mine shaft, nearly drowning, etc.) but no death of any of the protagonists.
A buffalo is seen falling from a high mine shaft track to an abyss down below (the buffalo later resurfaces unharmed).
Wesley pushes Maggie roughly, making comments hinting that he is going to sell her to a slaughterhouse.
Various characters are booted and/or kicked in the buttocks (intended to be comedic).
A horse uses his reins to knock guns from rustlers' hands, kicks a few of them and when one pulls a knife, the horse uses the reins to grab his hand and pull him forward so that he can kick him. We then see that this was just a daydream/fantasy of his.
