Mighty Dinosaurs - Blue Version
Mighty Dinosaurs (77941) is the blue counterpart to a 2021 Creator 3-in-1 set, built from the same 174 pieces as its brown sibling but finished in cool blue tones instead. It follows the same three-in-one rebuild principle, with no minifigures included in either version.

What can I build with it?Description
Same build, different palette
This set shares its construction entirely with the brown version (77940): the same 174 pieces, the same piece count, and the same ability to rebuild into three different dinosaur models one at a time. The only real difference is colour. For anyone comparing both releases side by side, it's a clear example of how much a colour swap alone can change the character of an otherwise identical model, even though every single piece sits in exactly the same spot as on the brown release.
Cooler tones than the brown release
Dark blue and the lighter sand blue replace dark orange and reddish brown as the main colours, with black and white still handling smaller details like teeth and claws. The result reads as cooler and slightly more stylised than the earthier brown version, closer to how dinosaurs are sometimes depicted in water or night scenes than to a naturalistic reconstruction. It's a better fit for a shelf built around blue or cool-toned pieces, or for anyone who simply prefers a less naturalistic look.
68 part types, unchanged from the brown set
Part variety matches the brown version exactly: 68 distinct part types spread across 174 pieces, covering the specialised shapes needed for teeth, claws and body plating on all three possible builds. The parts list on this page details every colour used here, handy if you're after sand blue or dark blue elements specifically, or want to compare piece usage against the brown release before deciding which one to buy, or whether to pick up both.
A second option for dinosaur builders
As with the brown version, there are no minifigures — this is purely a building and display set. It's a natural pick for anyone who already owns 77940 and wants a second colour option for variety, but it also stands on its own for builders who simply prefer a cooler, less naturalistic dinosaur model over a warm, earthy one. Either way, the appeal sits in the repeated rebuilding rather than a single fixed result.
FAQ
- How does this set differ from the brown version (77940)?
- The build, piece count and rebuild options are identical; only the colours differ, with dark blue and sand blue replacing dark orange and reddish brown.
- How many models can be built?
- Like other Creator 3-in-1 sets, the 174 pieces can be rebuilt into three different dinosaur models, one at a time.
- Do I need the brown version to enjoy this set?
- No, it works as a standalone build with its own cool-toned colour scheme, regardless of whether you own the other version.
