Buy LEGO Alligator and Crocodile Sets

LEGO periodically brings out an official complete Alligator and Crocodile set. In 2021, the new set 31121, Creator 3-in-1 Crocodile, was introduced and features a crocodile with a bird and fish skeleton that can be rebuilt as a snake with a mouse or a frog with a fly.

If you’re lucky enough to find the LEGO Creator Ferocious Creatures Set #5868 on sale, you’ll have a fun 3-in-1 crocodile solution. However, because it is a 2010 release, this 416 piece crocodile set can be pretty pricy to buy online.

Another LEGO Creator set is the LEGO Creator BrickMaster Exclusive Mini Building Set #20015 Crocodile. It was also launched in 2010, has 89 pieces, and ranges in price from $1 to $50 – dependent on where you look online.

A more recently launched set, LEGO City Jungle Starter Set 60157, is from 2017 and includes a ready-made crocodile.
