Hmm.. not quite, Rik. A "Toggeli" is more like an incubus/succubus creature with deadly intentions that sits on the solar plexus of its victims (very much like the "Nachtmahr" in Füssli's iconic painting "Nightmare
“) and similar tales exist in many (remote) cultures.
The "Sennentuntschi", however, is something that's man-made - at least in most cases. It's normally a (female) doll constructed by an alpine herdsman to keep him company.
Since a lot of alpine farms are totally cut off from the villages in winter, herdsmen would carve, sew or otherwise construct human-like dolls to feel less lonely and abandoned and to prevent cabin fever.
This might sound like a low-budget version of a blow-up doll, but "Sennentuntschis" are more like Roman penaten or maybe even voodoo dolls, or maybe comparable to the creations in the Pygmalion myth. They represent something that's not present but should be and they often have a deeply auratic presence.
There's a German article about them on Wikipedia
- maybe you could babelfish it or something.
