Some of these pictures and descriptions may give away plot details that you might not want to know before watching the film.
The most annoying woman ever put on screen, a nightclub singer named Willie Scott (Kate Capshaw), is camping aginst her will in the jungle at night with Indiana Jones (Harrison Ford.) She starts screaming when she grabs a fruit bat hanging on a line instead of her laundry. She screams again when she finds a monitor lizard sitting on a branch. Indiana Jones tells her to sleep closer to him for safety. Willie thinks he's trying to get fresh with her and tells him she'd be safer sleeping with a snake. Then a snake drops from a tree onto her shoulder. She thinks the snake is the trunk of an elephant that was grabbing her earlier so she tells it to "cut it out" and grabs the snake and throws it to the ground, thinking that she's throwing the trunk off her shoulder. When Indiana sees the snake, is freaked out, of course, because he famously hates snakes so much even statues of them scare him. He should be more scared of Willie.
The snake is a Burmese Python.
Indiana Jones and his annoying side-kicks Willie Scott and Short Round (Ke Huy Quan) are in a Maharaja's palace sitting at a large dinner table when a servant brings in a large silver tray with a python wrapped around a centerpiece. One of the Indian men is excited that they have been served "snake surprise." When the snake is cut open it is full of live eels crawling around. Willie and Short Round are too discusted to eat anything, but we see an Indian man swallowing some of the eels whole. Later we see people eating large black bugs and other unusual food including eyeball soup and chilled monkey brains served inside a monkey skull. It's all done for comedy, but really it's just a way of making fun of another culture by making their food look disgusting which is a cheap shot and maybe even racist. They used a fairly realistic fake snake for the scene and live eels, but I think the audience is supposed to think that it's a real dead snake stuffed with live snakes.
