Hydro

"Hydro earns a Skip It verdict with a BrickScore of 48.8: critics are largely in agreement that this MCFD Mixel is a lazy rehash of Lunk with non-functional wheels and a conceptually confused design, and it is worth seeking out only for completists or parts hunters."

Reviewers are divided but lean negative on Hydro, with Brickset calling it the weakest Mixel in the MCFD tribe and perhaps in all of Series 8, while JANG finds some merit in the highly articulate eyes and arm range. The core criticism across both expert sources is that Hydro is essentially a recolored version of Lunk with a ladder jaw substituted for a long neck, offering minimal creative differentiation. Owner ratings on Amazon average 4.3 out of 5 across 61 ratings, and the two LEGO.com raters gave perfect scores, creating a notable split with the expert consensus.

Where they split: The expert-owner split is sharp here. Brickset rates it 35 and calls it the weakest of Series 8, JANG gives it a middling 62, and the BrickScore lands at 48.8 for a Skip It tier. Yet casual Amazon buyers average 4.3 out of 5, and the tiny LEGO.com sample gave 5 out of 5, suggesting owners who pick it up without comparative context enjoy it well enough at the price point.
