Hey, it's Wall-E! No really, that's freaking Wall-E! That HAS to be a shout-out. Anyway, this was great because of its amazing animation. It didn't need to have dialogue. This actually makes a lot of sense.
The Universe is mostly empty space. Who knows of the infinite things that are going on in space? Aliens and other intelligent form lifeforms could be doing anything out there. This was just so bright and colorful too. It turned into the Cave of Wonders at the end!
