The second LEGO® Creator 3-in-1 set I’m reviewing is a lot smaller than 31120 Medieval Castle. But size doesn’t matter, as long as it brings us some new elements. Let's take a dive into the Fish Tank.


The set contains 118 different elements, with 352 parts in total quantity. The tank itself uses a lot of black elements, but the fish in the tank bring a colourful palette for you to enjoy. There are no new moulds, prints or a sticker sheet.

We welcome 4 new recolours. I’m most excited about the 2 SNOT bricks, expanding the possibilities of colourful MOCs.

  • 4 x Plate 1 x 12 in Dark Azure (6185543 | 60479)
  • 2 x Brick Special 1 x 2 with Studs on 2 Sides in Bright Orange/ Orange (6345590 | 52107)
  • 2 x Brick Special 1 x 1 with Studs on 2 Sides in Bright Purple/ Dark Pink (6334462 | 47905) 
  • 1 x Brick Round 3 x 3 Dome with Center Stud in Bright Reddish Violet/ Magenta (6290543 | 49308)

Rare parts:

  • Cone 3 x 3 x 2 in Bright Purple/ Dark Pink (6310205 | 6233) has appeared once before in a 2021 Friends set.
  • Brick Round 2 x 2 Truncated Cone in Bright Purple/ Dark Pink (6329278 | 98100) has only appeared in the 10280 Flower Bouquet.
  • Brick Round 2 x 2 Truncated Cone in Bright Bluish Green/ Dark Turquoise (6278463 | 98100) also appears for the second time.
  • Slope Curved 2 x 1 Inverted in Light Purple/ Bright Pink (6296041 | 24201) has only been seen in 2 sets, the last one being 76199 Carnage.

Also worth mentioning is the quantity of brackets in this set. You get 78 pieces of various 2-wide brackets, along with some extra 1-stud wide and 4-stud wide brackets.


As usual, there are 3 models in this set. I must say, only the Fish Tank seems really interesting to me, but I’m ready to be surprised.


Model A is the Fish Tank. The base is made out of Brick Yellow/ Tan plates, surrounded by brackets. So far, so good.

The tank is done pretty fast. I do have a hard time liking it. There is grey and blue sticking out and the sides have a thick part near the bottom, with a very slim clip connection underneath it. It just looks messy.

The saving grace of the model are the inhabitants of the tank. There are 5 cute fishes, a submarine and coral decorations.


Model B is a treasure chest, along with some mini-builds. The model uses 224 parts, of which a lot are brackets. 

What can I say? The multitude of colours in the brackets disrupt the looks of the chest. It feels like a prototype model where the designer used whatever colour of part was within reach, and then forgot to update the colours for the final model.

Again, the mini-builds save the model a bit, but this is really not doing it for me.


The third model is an easel with a canvas, using only 160 parts. Again, I’m not a fan of the distracting colours in the easel, but as a build, it works very well. It could work as a small display piece. I like the idea of adding a canvas. Most readers of New Elementary will of course immediately design their own paintings.


As you might have noted, I’m not liking the models in this set. The Fish Tank has a great interior, but the tank itself needs some colour swabs for me to work. The treasure chest, well, it’s a direct skip. Weirdly enough, I like the smallest model, the easel, the best. With ‘the best’ being relative to the other models.

You do get some nice recolours with this set. And besides a load of brackets, there are also some black tiles to be found but they can also be found on Bricks & Pieces, so I’m not sure if the set is worth it.

  1. Ooof, yeah this seems like a total miss from Lego. Not a good display set, but also not a good play set. It really does seem table-scrappy where they neglected to finalize some building solutions and do final color swaps to make it all integrated.
