I think this was one of my favorite episodes that I worked on! I just thought the idea of Steven and Connie in a bubble was really cute and they visit so many cool places in this episode. The underwater stuff was heavily inspired by Super Mario World!
"Yesterday’s full moon, shortly after sunset, rising over the illuminated Tyn Church in the Old Town. Right in time for Halloween! One of my favorite angles to watch the moonrise from." - David Tschorn
