[Warning – mature themes in this 7 minute short]

From 2011, but still featuring the most terrifying witch puppet as the central figure: YouTube link

I would buy the lead as a figure in an instant.

Not sure what was "mature" about that. PG, borderline PG-13 for the "skeletal birth" stuff. And then it all went nowhere. "Creepy witch makes skeleton baby out of a pumpkin and a long-decayed corpse, sticks it on skeletal tree, has apparently done it before. Nobody actually harmed or threatened, because no other characters in film." Yawn.
Kudos for the effective stage dressing, especially in the mausoleum sequence. Minus for the witch hat, which was obviously purchased off a Halloween aisle at store. (Ditto the gloves; too modern, too clean.)
In the end, the whole thing is more grotesque than terrifying, and not really all that grotesque.
The short needs some hint of an actual threat against a relatable or innocent target (or targets), or some sort of motivation for the witch's actions besides "just being a witch," as well as a resolution as to what the skeletal pumpkin monster can do or will cause to happen. So as a bit of horror, it's just meh.

Shouldn't be too hard to make the figure, though, as the face of the puppet is distorted anyway, so you don't have to be a particularly deft sculptor to pull it off. The rest is just one big tent of a robe (drags the ground all around) and a twisted pointy hat.
