There are four riddles in this short movie. It's pretty neat! The answers are actually subtly given, but if you're just watching the movie, you may not catch the clue; especially the fourth/final one. If you want to solve the riddles before the answer is subtly posted, here are the spoiler marks so you can pause before it's shown:
