This cute little fellow is a Cavey. They’re designed and sold by A Little Stranger for less than a tenner. The model here is a vinyl Cavey but you can get plush Cavey creatures too.
The name is a play on “Cavies” which is the scientific name for guinea pigs. They’re popular with collectors and I’m especially found of this gentleman Cavey.
Mike Strick took modding Caveys to a whole new level; far beyond adding a hat. Mike didn’t go for cute, either, he went with kick-ass and with werewolf.
You can see the walkthrough, complete with pictures, on his sculpting site. The result of his hardwork? It looks like this!
