For the first time in history, it's gonna start raining mobs! Entry level XP farm

Anyone who gets the song reference by the thumbnail and title, good job! You deserve to leave a thumbs up for yourself on this video!

I tried getting this video trimmed down to be able to do a short, but there's too much involved, so no tl;dr short this time.
