plaster of paris moulds - where do I get them?

[Sausagenbacon]

...and do they exist?
When I was young I remember there were p of p moulds, about 6" high, but I can't find them anywhere. I had a mermaid, but remember all sorts - pengions, lions etc.
I'm not thinking of fridge magnet size, which I have found.

Hobby craft have them

Unfortunately not. I bought the p of p from them though .
