Love this thread!
Adding one: Jungle Ride, as you're in the queue close to where you will board the boat, there is a table with a caged tarantula spider in it. If you put your hand close to the side nearest the queue of people and move it, the spider will "run" across the cage, causing it to tip up on its side, as if from the spider's momentum as it tries to "get" you.
I've been on this ride a dozen times and never knew that till DD18 and I were waiting in line, a little boy in front of us pointed to the spider and asked his dad if it was real. And I giggled to alleviate his fears, then put my hand there and wiggled my fingers saying, "Come here, spider!" and then the cage moved. Everyone nearby jumped. LOL! You have to put your hand at just the right spot, though, so if it doesn't work at first, just try a bit. Clearly it's got a motion sensor somewhere. Have fun!
