Today over the span of about two hours I created 12 frames of video.
The most difficult part was getting in the snake to properly wrap itself around the upper marble splitter and not have the orange marble fall every time.
In the background the gluer walked through the bridge and the blue marble and the pink character to come glue at piece near the foreground.
Also in the background, The reversible guy is picking up two pieces which will lead to the bridge.
