Great looking set. I really am curious about this new tree and how it can be manipulated. The overall set looks very much like the old tree house. Couldn't the design team just started from scratch instead of reinventing the same concept. It would have added diversity.
The addition of the not so mysterious part is the best news of the set. I will been needing about half a dozen of those parts to restore missing caboose pipes. The light grey can be painted
Is the part really not on the instructions? We need part numbers to avoid having to buy 6 sets, not that I would complain getting 6 grizzlies.
