I watched an episode of "The Amazing World Of Gumball" that had the exact same premise. I think it was probably done better. Of course, he wasn't a cloud. I really liked the animation in this. It was cool to see how unique the designs of the crawlers were. I loved how you could see the back of that one guy's eyes when he was facing away.
Those guys look like giant gumdrops. That would explain the bite mark on his side. The funniest part was probably the bit about the hallway. While not great, definitely good. I hope you had a merry Christmas!
