31078 Treehouse Treasures
Creator 3-in-1



Ooooh, a pirate boat? No, a treehouse! Wait, it's a pirate boat again... wha - it's a treasure cove now? Aaaah, it's a 3-in-1! What a lovely set, great parts, lots of play value. It immediately caught my attention when I was trodding along the aisles of my local supermarket. Who doesn't love pirates, anyway? And don't you dare to say "Nay" when I swing my rapier in your general direction... Arrrr! Having built 6289 Red Beard Runner lately, I just can't wait to get this started, so let's set sails and head over to the ->


Number: 31078
Title: Treehouse Treasures
Theme: Creator 3-in-1
Released: 2018
Part Count: 260 pieces

Retail Price:
DE - 29,99 €
GB - 29,99 GBP
US - 29,99 $
DK - 270,00 DKK

With 260 pieces, the retail price of 29,99 € equates to a price of 0,12 € a piece. This is in the higher range for 2018 creator sets. In comparison, set number 31072 Extreme Engines comes down to 0,09 € per piece. And the 31074 Rocket Car is even down to 0,08 €. Well, I'm not sure the parts of latter set will be of versatile use with those strange colours... Funny enough, all 3 sets have been designed by the same person: Jeremy Luettgen. He has also been active designing some of the Mixels.
Anyway, given the basic and tuned down colours of this set I think it's worth buying it for the retail price.

Set out on pirating treehouse adventures!

Enjoy imaginative pirate adventures with this LEGO® Creator 3in1 31078 Treehouse Treasures set, featuring a 3-level pirate ship treehouse with a ship deck, ship’s wheel, treasure chest hideaway function, bowsprit with flag and teddy bear, crow’s nest, tire swing and an upper-level den. Pirate accessories include a hat, telescope and 2 swords. This 3in1 model rebuilds into a Pirate Ship or a Skull Cave for more pirating fun, and includes 2 minifigures rigged out for pirate adventures, plus a scary spider figure.




As with all the Creator 3-in-1 sets, the front features the LEGO logo, set number and the main model in all it's glory, claiming three quarters of the available space. To the right we can have a look at the two alternative models. The age range is given as 7 to 12 years. While the lower limit seems quite fitting, the upper limit makes me wonder if I'm really too old to play with it... *makes sad face*

The back shows the play features for each of the 3 sets and a link to the LEGO Creator homepage. You can also see the tabs to press in when opening the sets. I have to say that I am impressed by the simple look of the packaging. Nothing too distracting, nothing much to shift your attention away from those wonderful builds.




After prying open the side, we have 3 bags with pieces, 1 Green plate 8x16 and 3 instruction booklets in our sweaty hands (or, hand and hook if your name is Captain Red Beard). We will get to the instructions later, so let's take a look at the pieces now.

The Arch Bricks 1x5x4 in Dark Brown are nice parts for castle or ship builders. The Wedge Plate, 8x8, Cut Corner in Dark Azure is unique to this set.


The Round Corner Tiles, 4x4 (called Maccaronis as I understand) in Medium Dark Flesh are also unique to this set. The wood planks are prints, overall there are NO stickers in this set. The decors are all printed. The short wood plank (1x3) together with the longer ones pictured here (1x4) can also be found in 21310 Old Fishing Store. 2x3 Tiles are quite new to me, while in fact they have first appeared in 2016.


There's also a treasure chest in Medium Flesh in this set, which adds to the play possibilities. However, I do have a bit of a problem with it: You can close the lid, but as there is no resistance while closing it opens on it's own if you turn it upside down. Having some old-time sets around here and also a chest in brown (from the 80ies or 90ies?), I was wondering if they had the same problem? Well, nope. They do have a bit of a resistance while closing, maybe related to that pin on the lid, and they definitely do not open themselves without assistance. Seems LEGO employed some mold change, as the older ones are also missing those 2 ridges at the inside front.




Minifigures - FrontMinifigures - Back

This set features 2 minifigures, a boy and a girl. Both minifigs have a single sided head, yellow arms, short legs (non-posable) and torso prints on front and back. The boy has a lime hoodie, while the girl features a white shirt with green print. It also includes one of these nice little teddybears with a torsoprint. While both minifigs are unique to this set, both torsos have seen use in other sets too - the boy's torso in 10260 Downtown Diner, the girl's one in 10261 Roller Coaster.
As accessories, there is a pirate hat with a feather. 2 spare feathers are also included, which is a nice treat as those small parts have an affinity to getting lost. The plume feathers are not on a sprue, as LEGO has done in the past with Pirates or Castle sets in the 90ies, but come loose in the bag. However, there is no "normal" hair piece included for the boy, if you decide to make your place somewhat less pirat-ey. 2 pirate swords are present along with a golden telescope and a printed 2x2 tile with a treasure map pattern to complete the play experience.



Instructions 01Instructions 02

Instructions 03Instructions 03

Overall, the instructions are nice and clear to follow. No printing errors or other mishaps. Instructions of the main model start with building the minifigures and continue with a somewhat ridiculous Step 1... When you are finished with building model A, the play feature is explained on the left side. On the right we have some more models available from the 3-in-1 series as house advertising (Avast ye bastards, look at that Pirate Coaster set ... ahem... Excuse me for getting a wee bit distracted here....).

Parts List

The parts list is in the back of model B.



Building Progress 01Building Progress 02

Building goes along without any troubles. As stated in the last paragraph, the instructions are easy to follow. Progress goes bit by bit, sometimes only 1 or 2 bricks per page. Alas, I'm getting older and older, so I won't complain about that. There comes the day when I'll be happy about it :D

Building Progress 03Building Progress 04

What amazed me is the stability of the construction. I had the opportunity to build set 31080 Modular Winter Vacation and that thing just disassembled itself after 5 minutes of play time. In stark contrast, the Treehouse is rock solid and will surely be better suited for heavy play.

Building Progress 05Finished

Nice little details here and there, like the little rocks in the water and the spider waiting to catch those nasty little ki... err, let's just say it is waiting for prey.

Here are the left-overs after building the main model:

Leftover bits



Play Functions 01Play Functions 02

Play feature No. 1 definitely is the hidden treasure cache in the tree trunk. There is a little flap with a lock on it, which can be raised manually. The flap itselfs sits on a bar which is held in place by 2 blue technic pins. Behind that flap is space to hide the treasure chest. This chest can be ejected with the help of technic axles and axle connectors at the other side of the trunk.

Play Functions 03Play Functions 04

Other play functions are the openable top room (sides and rooftop) with crows nest atop, the tire swing and the ships bow with the steering wheel. Not to forget the slide at the side of the treehouse, which can be raised to be used as a plank.

Play Functions 05

B MODEL - PIRATE SHIP :pir-grin:

B Model Pirate Ship - FrontB Model Pirate Ship - Back

A lot of parts are left unused, which could have been integrated easily. Therefore it's a pretty straightforward build experience and the B model is thus lacking a bit in play value. There is the crows nest and the lower deck with the spider in it. A posable rudder is present at the back and the steering wheel is now in the right place. I wonder why the treasure chest is placed on the deck, it may better be kept below deck.


Oh well, as luck would have it our unexperienced seamen have a rather unpleasent encounter at sea.

Seems someone else noticed that treasure chest too. Some useful armament wouldn't go amiss on this little bark. Maybe throw that teddybear over to soothe those angry pirates?

Fake vs Real Pirates



+ Adorable A and B models
+ Lots of play value
+ Nice, tuned down colours
+ 3 full grown instructions booklets
+ All prints, no stickers!

- B model could have been better
- C model does nothing to me...
- Somewhat higher part price ratio

Design: 8 / 10
Build: 8 / 10
Playability: 9 / 10
Minifigures: 7 / 10
Price: 7 / 10

Overall: 7,8 / 10


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" 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. I can repeat it over and over again: All prints, no stickers! I guess that's also the reason why the price per part ratio seems a bit unfavourable. All in all a very nice set. :thumbup:


Captain Sparrow vs Treehouse Boy

Thanks for the review. Any creator set is always filled with interesting parts and this is no exception.

Inspiration from classic Pirates sets are definitely sprinkled on several LEGO Creator sets that came out as of late and this set is one of those sets that I will definitely put in my shopping cart once I see a decent discount.

Thank you and yes, indeed it's a nice parts selection.
I have bought on discount as well. As I am more of a "classic collector", I mostly try to get new interesting sets on a discount and save up my money for hard-to-get sets from the 80ies and 90ies.

Regards, Chris

$20 here in China (Authentic). But I still don't buy it. One of the worst set ever

Thank you for the review, I was thinking of getting this and now I think I will. It's a cute little set.

This set is definitely on my list. The build itself is cool and it has a nice selection of useful parts. No stickers included makes it even better. I think this set could easily be expanded to create a more detailed tree house or ship.

@ks6349 Hello there! (Sorry, but I don't know your name) Can you please elaborate a bit more? Why do you think that this set is bad? What do you think could've been made better?

@Park7573 , @ScaleCarModels & @LEGO Train 12 Volts :
Thanks for commenting and your input! If you buy 2 of it, the parts should be sufficient enough for a bigger and even better tree house. All those dark green and green plates are so nice for landscape sculpting.
But I think there might be an order via Pick a brick or Bricklink necessary if you plan to build a decent ship. :wink:

Cheers, Chris

@Capparezza Hi, I shopped around and found this set, it was pretty great value, only approx usd 19 here, but I can't see the reason of getting this. It's difficult to be compatible with my Lego city and the other modular buildings unless I am doing a lego city full of mountains and hills. For the Creator 3in1 series, I like 31026 31036 31065 and 31068, I've got all of them reasons are simple, they are more "compatible" to style of other buildings

Just a thought about City compatibility, you could always build the pirate ship and call it a play structure at a playground for your city's tots...

@ks6349 Sorry for the late reply. I was busy washing and sorting a huge load of LEGO, and later on holidays :wink:

Indeed, if you are looking for something to complement your city layout, it might not be something to take serious at first sight. There are definitely better sets to get if you intend to build an impressive layout. However, as @DarrellBricker pointed out, it might still be feasable as playground or even as a side build for a smaller town layout.

And don't forget the "mod-ability": Build a bigger tree using two sets, use the leftovers for buildings, use the parts for landscaping.... or what else comes to your mind. That's the good thing with those bricks, you can build whatever you like with it :laugh:
