Retailer reviews
Summarized retailer review data when available.
Lego always on the expensive side but this is a great set. My boys loved it.
A little overpriced, but a cool Lego!
Three models are made with the same pieces, and they are very nice. My grandchildren loved them.
Fantastic set. Not for the crocodile itself, but on YouTube, at Bricksmart, you can find all sorts of workshops to make a variety of reptiles. With this set, we have already made a frilled lizard, a chameleon, and an axolotl. A super fun combination between watching YouTube and building according to the instructions.
My nephew loved it, very educational
LEGO never disappoints and Amazon is always accurate with shipping. Great product. You can build several characters. Really great.
Very nice set. Fun to build and play with.
My grandson can build 3 different animals with this LEGO set.
