Review: LEGO 31140 Magical Unicorn

March 2023 saw the debut of a pretty big lineup of new Creator 3-in-1 sets, a theme that I have always enjoyed because it always feels like the purest and most creative LEGO experience.

Add in the ability to build and rebuild 3 different models in a set, and you have everything you need for a fun LEGO kit that provides plenty of fun.

One of the Creator sets I’ve been looking forward to picking up was 31140 Magical Unicorn, which drew me in with its vibrant colours, cute builds and most importantly, a really affordable US$10 pricetag.

Here’s a quick review of the rainbow-powered Creator Magical Unicorn set, which is Creator 3-in-1 at its very best!

31140 Magical Unicorn is available from, or Amazon and in Australia, you can pick it up for AU$10 from Kmart.

At AU$10, I wasted no time in picking up 3 copies of the set for this review, mostly because I wanted to build all 3 models and display them simultaneously, but also because I got lazy and wanted to avoid breaking apart the sets for each model.

31140 Magical Unicorn Group

There are 3 models that you can build from 31140 Magical Unicorn – a peacock, a magical unicorn and a seahorse, all of whom feature bright and vibrant rainbow colours.

At US$10, these are really great impulse buys and you are still guaranteed a great LEGO building experience, all without the need to break the bank, which is why I really appreciate LEGO Creator 3-in-1.

Peacock Model

31140 Magical Unicorn Peacock

First off, let’s take a look at the Peacock, which was a design contributed by LEGO VP of Design Matthew Ashton, which he has adoringly named Ploomella or Ploomelope.

31140 Magical Unicorn Peacock Bill

I wasn’t expecting to like the Peacock build, but it’s such an adorable model, and there are some really great distinctive features such a his yellow beak, and teal/blue crest on his head.

With his big eyes, and dashing crest, he just looks really sassy, and he knows that he’s the best-looking peacock and isn’t afraid to strut his stuff.

31140 Magical Unicorn Peacock Tail Pattern

A really nice bit of detail is the Peacock’s Tail, which utilises some really clever and gorgeous tile-work, alongside some slope elements for some added texture.

All in all, a really cute and sassy Peacock!

Seahorse Model

31140 Magical Unicorn Seahorse

Up next we have the Seahorse, which is a form that you wouldn’t expect to be done easily, yet designer Irma Svenningsson managed to nail the Seahorse’s distinctive silhouette.

The arched head, large rainbow-coloured belly, and twisty tail all come together quite nicely, and there’s even a golden horn to top the seahorse off, giving it a bit of a whimsical and magical vibe.

31140 Magical Unicorn Seahorse Side

Here’ a look at the Seahorse from the side for you to really appreciate just how accurately the shape was re-created here, which is helped by the base to balance it all.

31140 Magical Unicorn Seahorse Angle

There’s some limited articulation on the head and tail, and because of its height and it does look good on display, but the colours are a little loud here, and not quite what you’d expect from a seahorse.

Thankfully, it’s a magical Seahorse, so it mostly still works.

Magical Unicorn Model

And last but not least is the primary model, the Magical Unicorn. This was pure joy to build, and is so whimsical and magical that you can’t help but smile as you put it together.

The colours are simply magical, and this probably comes close to 31124 Super Robot as one the most enjoyable Creator 3-in-1 sets I’ve ever put together.

The blend of colours and wavy shape of the Unicorn’s mane and tail are superb, and I also like the hints of mint across the body that break up the mostly white background.

31140 Magical Unicorn Unicorn Rainbow Base

Here’s a look at the rainbow-patterned base which ties the entire build together.

One of the Magical Unicorn’s main drawcards is the level of articulation and how dynamic it is as a LEGO model.

It’s so poseable that it can easily perform all sorts of yoga poses and moves. I’ve taken the liberty to go by the naming convention that EllieVToys put together for the Unicorn’s yoga poses.

31140 Magical Unicorn Unicorn Trotting

And yes, it also trots along effortlessly!

What I liked:

  • Great selection of models to build that all have their own unique looks
  • Ultra-affordable
  • Plenty of colours to use for further creative building
  • Magical Unicorn’s articulation makes it so much fun to pose and display

What I didn’t like: 

  • Some alternate eyes would’ve been a nice bonus

Final Thoughts:

I had an absolute blast with 31140 Magical Unicorn, and I consider this a shining example of all that’s great with Creator 3-in-1.

For starters, the US$10 pricetag just screams affordable, and there aren’t any compromises with the LEGO building experience – rather the opposite as you get 3 models to build and rebuild, making this a great toy especially for younger builders.

Each different model has their own quirks and they all look pretty good, although I have to say that I’m partial to the Peacock because of his sass levels.

The Magical Unicorn is a superb model, with mesmerising colours, and plenty of articulation that simply invites you to play and put it in all sorts of funny poses.

31140 Magical Unicorn is easily LEGO Creator 3-in-1 at its very best, and I couldn’t have enjoyed this any more. Highly recommend this if you’re looking for an inexpensive whimsical LEGO set that packs plenty of fun.

Build [4] – Really fun varied builds for all 3 models
Real Value [5] – At US$10/AU$10, this is unbeatable value at this price bracket
Innovation [4] – Creating animal forms at this price level and piece count that look accurate is awefully impressive
Coolness [4] – Some people might be put off by all the rainbow colours, but I love how whimsical it looks, and the posability of the Unicorn
Keepability [4] – This is great set to play with, or even display a you’re invited to change up the Unicorn’s poses

Rating and score: 4/5 ★★★★✰
