WILLIE: I hate the water, and I hate being wet, and I hate you!
We need to put emphasis on the "man" in "man and the natural world." Indy, who's an archeologist and male, is comfortable with anything nature throws at him. The one woman in this movie is not a fan of nature.
[Willie puts perfume on an elephant, which knocks her into the water.]
Willie is comically inept when it comes to anything nature. You'd think she's never been outside in her life the way she acts. She teaches us to leave animals alone and let them do their business.
INDY: Those aren't big birds, sweetheart. They're giant vampire bats.
We don't think there are any cuddly animals in the jungles of India. It seems like everything might kill you at a moment's notice.
WILLIE: I was happy in Shanghai. I had a little house...and a garden. My friends were rich. We went to parties all the time in limousines. I hate being outside! I'm a singer! I could lose my voice!
We're not sure why Willie doesn't just stay in the village if she hates being outside so much.
WILLIE: I hate that elephant.
In a bit of irony, Willie mistakes a snake for an elephant's trunk and she simply flings it aside. And you know how Indiana Jones feels about snakes. It's a funny bit of accidental bravery on her part.
WILLIE: They're all over me!
Unlike the dinner scene with crunchy beetles, the bugs in the cave are
real. Over 80,000 bugs were used in the cave. The actors freaking out
over the bugs? That's not acting. (Source)
