Melting Olaf

My submission for Day 19 of Replit Creates, following the prompt "Write code that someone else describes to you."

I asked someone I know to give me something to build for this day's prompt, and in the end, they told me to turn Olaf into a puddle. That's what this is. Enjoy! (By the way, no images are involved in this. Everything that you see is just a bunch of HTML elements which are styled with CSS to look like Olaf and a puddle.)
