Some of these pictures and descriptions may give away plot details that you might not want to know before watching the film.
Bill's group is called the Deadly Viper Assassination Squad. Bill is Snake Charmer, Beatrix Kiddo is Black Mamba, Elle Driver is California Mountain Snake, O-Ren Ishii is Cottonmouth, Vernita Green is Copperhead, and Budd is Sidewinder.
Budd lives in a run-down trailer out in the Mojave Desert where Elle shows him a suitcase full of cash. We see him greedily pull off stacks of money until he sees a Black Mamba beneath them. (They used a real Black Mamba for the close-ups. They probably use a similar species for some of the other shots, along with an obviously fake snake hanging off Budd's face.) We see the snake strike and Budd's face covered with huge two-holed red spots. (Even though the real black mamba has small fangs and only needs to bite once, all movie snakes have two huge fangs and strike repeatedly That's the law.)
As Budd lay on the floor dying, Elle pulls out a list of fun facts about Black Mambas she found on the internet and wrote by hand in a small tablet. She then reads them slowly to him for what seems like the entire 20 minutes it takes the venom to kill: "In Africa, the saying goes, in the bush, an elephant can kill you, a leopard can kill you, and a black mamba can kill you. But only with the mamba, and this has been true in Africa since the dawn of time, is death sure. Hence, it's handle: Death Incarnate. Pretty cool huh? Its neurotoxic venom is one of nature's most effective poisons, acting on the nervous system causing paralysis. The venom of a black mamba can kill a human being in 4 hours, if say, bitten on the ankle or the thumb, however, a bite to the face or torso can bring death from paralysis within 20 minutes. … The amount of venom that can be delivered from a single bite can be gargantuan. … If not treated quickly with anti-venom 10 - 15 mg can be fatal to human beings. However, the black mamba can deliver as much as 100 to 400 mg of venom from a single bite."
Enter Beatrix, and a lot of really nasty sister-fighting ensues, including a bunch of still shots of bloody faces for the movie posters, dozens of gallons of blood spread all over the trailer, a lost eyeball, and a trailer completely torn to shreds. Finally, the Black Mamba rears up one last time to say goodbye and we go to the next chapter.
