<p>We have ten of these, but I don't know from which series! When pressing the yellow button it makes a sound that could be a train or a tractor or something like that. We are curious. Does anyone know?</p>

It doesn't look like any Lego piece I've ever seen. Does it have Lego written on it anywhere? Are there any numbers written on it? Any other angles?

I have updated the question with more info on the sounds it makes, and with an image of the back.
