"The Shark Skin sits in Mixed Reviews territory at BrickScore 66.4: it earns genuine praise from Brickset as the most compelling FORMA skin with an authentic swimming mechanism, but The Brothers Brick found it a letdown in color and novelty, making this a worthwhile buy primarily for FORMA newcomers rather than those who already own the base Koi model."
The LEGO FORMA Shark Skin (81001) earned a BrickScore of 66.4, landing it in Mixed Reviews territory, with the two expert reviewers split on its appeal. Brickset called it the best of the four FORMA skins, praising its smooth swimming mechanism and realistic appearance, while The Brothers Brick was more tepid, finding the color scheme unexciting and the initial novelty of the FORMA mechanism already diminished after experiencing it with the base Koi model. No owner data is available for this set.
Where they split: The two reviewers disagree meaningfully on the shark's appeal. Brickset rated it the best FORMA skin and praised the mechanism as ideal for a shark. The Brothers Brick, having already experienced FORMA with the Koi, found the shark underwhelming in color and novelty. This divergence likely depends on whether the buyer is new to FORMA or already owns another skin.

"As much as I had initial excitement when I first saw the release of the shark skin, the final result left me a little less enthusiastic. The color scheme isn't very exciting, and perhaps I missed the mystery of the movement, which I'd already discovered with the application of the first Koi Skin placement."
