Is this a wind up toy?

This is my sister Babette on her walk this Tuesday (before we had our fur shaved off yesterday). She often comes across this little thing on her morning walks. I haven't had the pleasure of meeting one of these and I think it looks like a nice toy to play with. I see in this photo that Babette is doing her full-on 'play with me' routine - so it must be a toy that moves!
