J.B.'s Submarine

"J.B.'s Submarine earns a Skip It verdict with a BrickScore of 58.7. The minifigure lineup is genuinely strong, but the submarine itself is the weakest vehicle in the Hidden Side range, with stubby proportions, sticker-heavy details, and a scale that disappoints relative to the theme's other offerings."

J.B.'s Submarine received a BrickScore of 58.7 (Skip It), supported by two expert sources that diverged meaningfully in their assessments. Brothers Brick gave a cautiously positive 72 for its fun quick build, attractive color scheme, and quality minifigures. Brickset scored it 45, cataloguing an unusually long list of structural and design failures for a Hidden Side vehicle set. Owner ratings lean toward the Brothers Brick view: 1,023 Amazon ratings average 4.8 out of 5, but the sample is nearly entirely Amazon consumers with minimal critical engagement. Both expert reviewers agreed on the minifigures as a genuine strength, but Brickset concluded the submarine itself was a clear step below the rest of the Hidden Side vehicle lineup.

Where they split: Brothers Brick (72) and Brickset (45) split meaningfully. Brothers Brick focused on fun factor, color, and minifigures; Brickset conducted a detailed structural critique and found the submarine significantly weaker than other Hidden Side vehicles. Both agree the minifigures are the set's primary strength. The wide owner rating (4.8) aligns more with Brothers Brick than Brickset.
