I remember reading that originally there was to be a "reprise" of the song "Anything Goes" during the scene where Indy, Willie and Short Round are riding the elephants. Willie starts singing to herself, Indy and Short Round join in(!), and her singing is actually what prompts the elephant to squirt her off its back. Not sure if this scene was actually filmed and then edited out, or if it just never made it into the final screenplay. In any event, I remember this scene was in the novelization that came out at the time and wishing they'd included it in the film!
