I'm pretty sure these are GW horrors but they are larger then my mental image of the regular horrors and the bag had them labeled as 'purple horrors' but Google gets me nothing and Solegends hasn't helped much, especially since very few of the images on their site have them with spiky tails. Any ideas?
I included a few random things for some semblance of scale.

Third edition Chaos Daemons (mid 90s).

They'll either be pink or blue horrors; most likely pink. The blue were a lot smaller, as when a pink was killed, two blue would appear in its place. Given that yours are larger than a skaven...

No idea what they're worth, but I wouldn't eat them. A recent study suggested strong links between violent crime and levels of lead in the bloodstream.

(No idea about their value, but I suggest following Nazgob's advice.)

takes me back, haven't seen any of these in an age.

I wouldn't eat the penny, skaven thrower or the lipsyl either, if I were you. The "Viz" books (videos?) in the background are likely perfectly edible, however.
