Music Train is a bump and go musical locomotive from an unknown company. It is a bootleg of the Shelcore shaking railway locomotive (credit to _ksllmfcai_ for this info).
The toy is only known to have been produced in two color variations.
One version is yellow with an orange face, cab roof, green funnel, and a translucent, yellow circle on its smoke box door. It has a white bear-like creature (probably a tanuki?) on the roof of its cab, holding a green, stringed instrument. The locomotive also has orange pistons.
The other version is green with a yellow face, an orange funnel and pair of pistons, a yellow cab roof, and it has the same creature with the same colors, sitting on its cabin. I don't have a photo showing this one outside its box, though.
The locomotives have black eyes with a small, red triangle in each, and a nose and mouth. It also has white eyelashes.
The toy moves around on bump and go wheels while moving its eyes left and right and blinking them. The box mentions it plays music, but this is unconfirmed, as there is also the possibility of it playing train sounds. The creature ontop of the locomotive is supposed to wobble, while the locomotive is moving about. Its mouth appears to be capable of moving.
