Earlier this year, it was reported that the LEGO House Tree of Creativity (4000026) would be retired and a new exclusive set would be taking its place. Fast forward to today, we now know of the set thanks to Brickset which is the Wooden Duck (40501). The building instructions were found uploaded to Customer Service but it looks like they have been quickly taken down.
The set pays homage to the Wooden Duck created by Ole Kirk Christiansen that was released in 1935. Like with other LEGO House exclusives, I don’t see it being available online and will be only available at the LEGO House, unless you have connections or purchase them off the secondary market.
