It is a a sock destruction unit, but a very special one...
See that coloured collar around its neck? That means that it only destroys multicoloured socks.
They are also known to go for colourful hankies as well, among other things, so make sure to keep those out of reach, unless of course you're wanting them destroyed along with your socks...
