Make your small figurine revolve. This is the platform key you will need if your figurine has a standard mechanism inside. See image. The thread of the shank is will fit on the standard 18 note mechanisms. It is a replacement for a bottom wind up key and as it winds down it will cause your figurine to rotate. These measure 1.75" in diameter and are raw and unpolished white metal (could be steel). Not bright and shiny .... but they don't show.
