I hunted around the hitchhiker and critter I.D. forums for a while now and haven’t seen anything like this, if it’s there and I missed it I apologize. I turned off the blue light for this picture, critter in question is to the right of the little gsp clump. Antler looking thing started from essentially nothing around 6 months ago and is now roughly 6cm long. It is rigid, sways under the random flow generator a bit like a tree branch in wind.
