Koi Fish Reviews
Brick Fanatics
“40545 Koi Fish features 203 pieces making one Koi fish and a Fry, as well as a base to display the two of them on transparent stands made to look as if the two figures are underwater. Floating foliage completes the scene and you can find this build on shelves from August 1,... More 2022.”
Bricksfanz
“This isn’t the first fish to be given the BrickHeadz treatment, that honour goes to the Goldfish. But it does offer the biggest departure from the BrickHeadz format. Due to the nature of the fish, you’re basically just building what would be the head section compared to... More other BrickHeadz. Obviously, it has a lot more detail to it such as the tail and fins, but both fish certainly require a lot less building compare to other sets.”
