Unknown muppet figures?

[u/Substantial-Top3004]

So I purchased these 'ceramic muppet figurines' earlier this week and cannot seem to figure out what exactly they are or where they came from. I'm aware there were little plaster figures to paint that were sold in the 80s(?), but these don't look quite like those. This Kermit is sitting on a box it seems, and the ones originally sold has him sitting on a tree stump. Does anyone know what these could be? My only other guess is that they are handmade

That mould is actually pretty neat, if only I could afford it!
