Tree House Treasures Reviews
“This set has a lot of cool play features; adjustable plank, doors, roof, etc. The accents like the pull out chest and tire swing are great and all three builds look awesome.”
“We had a lot of fun with this set. We especially love the telescope and 2 swords. Plus, we really enjoyed rebuilding this set into something new when we were done with the Treehouse.”

“I couldn't be bothered assembling the C model, it's just too plain and definitely not a cave at all. But the treehouse and ship have been great fun to build and play with. While this set overall may not be outstanding to me, I would definitely put it into the "Above Average"... More category. It's play features and overall value due to the parts and colours and the fact that there are 3 full blown instruction booklets makes it worth.”

About Creator 3 in 1

Creator 3 in 1 sets come with instructions for three different models from the same bricks, built one at a time. The trick is in the design. Every part has to work in all three models, so the tiger of 31129 Majestic Tiger also builds a panda and a koi fish, and many builders keep the parts from a set as a starter supply of ordinary bricks.
3 in 1 was introduced in 2006 and currently consists of 252 sets. As of today,
4997 Transport Ferry is the most valuable 3 in 1 set with an estimated new/sealed value of $304.
Summary
Creator 3 in 1 Tree House Treasures set 31078 was released in August 2018, retailing for $30, but has since been retired. New, unopened Tree House Treasures sets are valued at $45, while used sets can be found for $27.
