"The 31121 Crocodile earns its BrickScore of 78.2 with a standout main model that Brickset called the best Creator animal to date, backed by an owner rating of 4.81 from over 1,000 buyers; the weaker alternate builds are a noted limitation but do not undermine the set's strong overall value."
Reviewers broadly praise the 31121 Crocodile as one of the strongest animal builds in the Creator 3-in-1 line, earning a BrickScore of 78.2 and an exceptional owner rating of 4.81 out of 5 from 1,088 buyers across three retailers. The crocodile main model draws near-universal admiration for its realism and posability, though critics note the alternate frog and snake builds are considerably weaker display pieces. Ninety-five percent of LEGO.com buyers would recommend the set.
Where they split: The only meaningful split is between the Brickset reviewer's structured analysis (which found the frog model notably weak and the movement range limited) and the uniformly positive owner reviews, which focused primarily on the play experience and build enjoyment. The expert critique of the alternates as non-display-worthy is not reflected in owner sentiment.

"Creator sets are a fairly good way to expand your building experience and techniques, mainly because you get the opportunity to build three times from the one purchase."
