The verdict

This one is quietly one of the better value plays in the January 2026 Dreamzzz wave, and the eagle mode is the reason I kept coming back.

You get two genuinely different builds out of 1,107 pieces for around seventy dollars, which is rare in this theme. Just go in knowing the poseability is softer than the box art suggests, and you will be perfectly happy. It is aimed squarely at kids who want a big transforming toy they can actually play with.

Best for: Dreamzzz kids who love a build that becomes two completely different creatures

The full review

What it is

The Crocodile Submarine is the second largest set in the January 2026 Dreamzzz wave, and it is the kind of LEGO® set that sounds gimmicky on paper and then wins you over in the box. The premise is simple. You build a chunky yellow submarine with 1,107 pieces, and that same base transforms into either a snapping crocodile or a wide-winged eagle. What got me was that neither mode feels like the afterthought. The croc is all attitude, with a posable head and legs and a long articulated tail, while the eagle spreads out with feathered wings built from layered wedge plates in a really pretty colour run. There is a cockpit that seats a minifig, dual shooters, a periscope, sword storage and a hidden compartment, so the play features are stacked. If your kid loved the crocodile car from the very first Dreamzzz wave, this is the grown-up follow-up they will recognise instantly.

The catch

Here is where you want your eyes open. For a set that lives and dies on transformation, the poseability is the weak spot everyone keeps flagging. The eagle wings and the boosters do not really move, so once it is built it mostly holds one dramatic shape. The crocodile has the opposite problem. It stands on fewer legs and tends to tip, so it leans on its tail like a kickstand more than you would like. The designer left extra parts in the box for people who want to tinker and improve the joints, which I appreciate, but out of the bag it is stiffer than the action photography promises. There is also a bit of parts inflation in places, where a handful of small elements get stacked to approximate a slope that one moulded piece would have done cleaner. None of this is a dealbreaker, but it is the difference between a very good set and a genuinely great one.

Who it's for

So who is this really for. If you have a Dreamzzz fan in the house who wants a big transforming creature to actually swoosh around the floor, this is an easy yes, and the price makes it one of the more sensible ways into the theme. Parents watching the budget will like that you are essentially getting two large builds for the cost of one. If you are an adult collector chasing tight engineering and articulation, this is not the set that will impress your shelf, and you will notice the stiff joints straight away. But for the intended audience, kids who want story, characters and a toy that changes shape, it lands well. I came away charmed, mild grumbles and all.

The parts story

What the build is actually like, and the pieces worth knowing about.

The build moves through the yellow submarine hull first, and it is a satisfying, logical assembly with a storage compartment, a one-seater cabin for Logan, a periscope and a row of six pipes at the back that honestly look like the exhaust of a big V12 engine. A trans-light-blue crystal creature gets worked into the middle as the transformation catalyst, which is a nice narrative touch. From there you commit to a mode. The croc adds the head, legs and that long jointed tail, while the eagle swaps in larger rebuilt feet and the wings, which are the best part of the whole build. Those feathers are layered wedge plates in a graded colour pattern, and watching them come together is the moment the set clicks.

On parts, the headline is a brand new mould: the large crystal dome (design 7591) appears twice here in Trans-Light Blue, and it is lovely in hand. You also get a nice clutch of first-time recolours, including a Brick Round Corner 3x3x1 with no studs in bright light orange, the spiked weapon blade in trans-dark pink appearing four times, and round corner 2x2 plates in dark blue. Add four minifigs (Logan with his collectible blue sword, Zoey with a bow, Arika with a scythe, plus a Grimspawn), two spiders and the collectible Blue Treasure Creature, and the roughly 6.3 cents per piece starts to look genuinely fair for the theme.

Fun facts

01The eagle mode is a clear nod to 2013's Legends of Chima set 70003 Eris the Eagle Interceptor, though Eris' original could fold its talons back in flight while this eagle's legs stay fixed.
02It carries a new mould, the large crystal dome (design 7591), which shows up twice in Trans-Light Blue.
03At 1,107 pieces it is the second largest set in the January 2026 Dreamzzz wave.
04The base submarine hides real play features under the transformation, including dual shooters, a periscope, sword storage and a concealed compartment.
