I have no idea why anyone would want to make speakers that look like M&Ms, let alone soft ones.
That being said, here they are. They have a 3.5 mm headphone jack that work with any MP3 player or PMP. I don’t know if this was a Christmas promotion, but it is available in just red and green.
You should be available for about $34.95 each, and works as plush toys.
