I can't upload a picture right now. There's a picture on my profile where you can kind of see it. In the picture, the snake is under it. It's free-form, there aren't any areas where the wood reconnects with itself to create a "hole", but there are areas where the "sticks" are screwed together to make narrow angles. Knowing that they can actually get stuck is enough. I'm going to take it out. I have other single pieces that are just mini-logs she can slither around on.
