why on earth are they worth so much now?

Because there is an achievement for feeding 25 of them to your pets. They were also recently asked for by the recycle beast.

oh i see thank you :) ^^ xx

what is the real price of one?

As far as I'm aware you can't buy them in any shop. You get them as a prize from Random.
