That was awesome and very unique compared to everything else uploaded to Newgrounds. It had a simple concept, but the detail added to it is just incredible. The movements were naturally toy-like, and thus made it seem as if I were looking into the imagination of a child, or the world that the toys live in. The song was fun to listen to also; it resembled some sort of carnival, and especially made me think of a merry-go-round (the style of the baby-faced dolls -- if they are dolls and not "action figures" -- reminded me of the glossy horses that spin on those). All-in-all, I really enjoyed this cute (and kinda creepy) short film. It was somewhat short, but the amount of effort put in makes up for that.
... Of course, I might have a little positive bias towards stop-motion (give me that Wallace and Gromit ;p ).
