A Sandman, a Carnivore, and a Shapeshifter Walked Into the HUB This Week…

It’s like the Sandman (if he was made from foam), and feels like a hug, like hearth and home. Carnivores may roll their eyes, but this is one plant that rides the sky. A wily shapeshifter, it morphs and molds, but its sense of fashion always holds. So, riddle me this and register there. And if you’re not in the HUB, then…where?
