My Aunt, Uncle, and cousin came today for Thanksgiving. My cousin is about 4-ish, and she likes LEGO Bricks. I've been teaching her about the Bionicle universe in simple terms for the past half-hour or so.
Me: "Basically, their entire universe is a big guy, called Mata Nui. He's, like, 40,000,000 feet tall. But this bad Maluta guy takes over his body, which is the universe, and sends his spirit out into space inside a mask."
Cousin: "Wow! Mata Nui is even taller than an airplane!"
