Your little teatable visitor is a Tom Clark Gnome from Cairn Studios. Officially, the Forest Gnome, although I'm confused on the vintage, since there are several of them, all different sizes, and it's clear that you have one of the small versions, for which I cannot locate any information. I cannot give you his name, because the name of the Forest Gnome is one of the most closely guarded secrets in all the forest, so I will content myself with calling him Forest*. The Poppets have decided they are going to call him The Dude. (They just watched The Big Lebowski last week, and currently EVERYBODY is "The Dude."
Whether or not this is your "Official Teachat Spokesperson," I can't say, since I don't see any posts labeled either "The Forest Gnome" or "The Dude," but it's still my final answer.
*There's also a doppelganger named "Gus" who really gets around. Less often seen is a traveling "twin" of Gus and the Forest Gnome, known as Lumwinkle
