Xmas gift for my grandson Cooper. He will be so excited to work on a project that has his name on it. This boy has grown up with Legos as have both his parents?

Cooper's Robot Dinosaur

LEGO

I almost missed this one and I'm glad I was able to pick one up (Feb 2026).  This may be a contender for my favorite LEGO DreamZzz set.  The build experience was excellent.  Very sturdy, lots of detail, interesting SNOT techniques.  there were 21 stickers but they were easy to apply and make the set pop.  Lots of pose ability.  I built the Trex and think it is the cooler of the two build options.  The minifigs are great. Cooper, Dooper, Zoey, Doey, and Sneak are all welcome inclusions.  The mini motor cycle that fits in the body of the Trex is cool.  I love the colors.  I was pleasantly surprised by the size, it was much larger than I had thought it would be.  A very good adversary for the Nightmare Raven.  It's too bad this set and theme didn't sell better.  This is LEGO at it's best and I fear too many enthusiasts are missing out on this collection.  Kudos to the LEGO DreamZzz team for dreaming these up!  The theme has rekindled my imagination for building and my love for LEGO.

Terrific Trex Set

3 in 1, choose your build! pretty friggin cool! bought as a gift for a 5, 12 and 14 year old to build together. they love it

My 6 year old really wanted to give this a shot and he loved putting it together. He has it "on display"

Go for it.

This set is massive and will give you hours of endless fun. There are different options of what to build for more fun too!

Two builds in one

Such a fun project for my husband and son to do together. I love that it can become 2 different dinosaurs so it truly can be an ongoing project.

Fun project

The price was great, that's why I bought it. I still haven't received it, but I have bought it in the past and know of it already.

This was the first Lego that i ever purchased brand new the was missing a whole bag of parts. This set has a lot of tiny little pieces, be careful. May be an issue with this model not being complete. Several others have reported yhe same issue about a number parts bag missing. Good Luck.
