NEW LEGO BrickHeadz April 2026: TMNT and Mandalorian

It's not often we get to bring you a round-up of new LEGO BrickHeadz sets, but with two TV tie-ins coming in April 2026, we've got your first look at both.

The new LEGO BrickHeadz sets for April 2026 are:

• LEGO BrickHeadz Teenage Mutant Ninja Turtles Figures (40878)
• LEGO Star Wars The Mandalorian and Grogu: Allies & Villains (40856)

Unusually, the LEGO Mandalorian BrickHeadz set features five figures instead of the usual four - but don't worry, iDisplayit has custom BrickHeadz display cases to fit both new sets.

LEGO TMNT BrickHeadz (40878)

Price: £34.99

Release Date: April 1st 2026

Ages: 10+

Pieces: 567

LEGO BrickHeadz Figures: 4

LEGO Insiders Points: 280

Size: Over 8 cm tall

First up on April 1st is LEGO BrickHeadz Teenage Mutant Ninja Turtles Figures (40878), which consists of the four title characters from the World of TMNT. In case you need reminding, that's Leonardo, Raphael, Michelangelo and Donatello, everybody's favourite sewer-dwelling mutated pet turtles with a love of junk food.

The brick-built heroes in a half-shell are holding ninja weapons (and a pizza, naturally) and can be told apart thanks to their different skin tones, coloured face masks and belt initials.

Although she's not included in this set, it's sweet that LEGO BrickHeadz 40878 releases on the first of April - a nod to the foursome's jumpsuit-wearing journalist friend, April O'Neil.

Did you know? The coloured eye masks worn by the Turtles are called 'domino masks', giving them an extra connection with their favourite food!

LEGO Mandalorian BrickHeadz (40856)

Price: £34.99

Release Date: April 26th 2026

Ages: 10+

Pieces: 661

LEGO BrickHeadz Figures: 5

LEGO Insiders Points: 280

Size: Over 8 cm tall

Later in the month comes LEGO Star Wars The Mandalorian and Grogu: Allies & Villains (40856), which packs in almost 100 extra pieces to make five figures instead of four. 

Three of these are full-sized LEGO BrickHeadz: The Mandalorian, Colonel Ward and Imperial Remnant Snowtrooper. Then there's a slightly smaller Anzellan Droidsmith and probably the biggest selling point for this set, a 5cm LEGO Baby Grogu BrickHeadz figure, which is squee-worthily cute.

Again, there are accessories to bring each figure to life, and you can mix and match with figures from other LEGO Star Wars BrickHeadz sets to create an even bigger display.

Did you know? The LEGO Mandalorian and Grogu BrickHeadz are wearing beskar armour, one of the few materials that can protect against a lightsaber strike.

How to display it

To display your new LEGO BrickHeadz sets this April, you'll need the right sizes of LEGO BrickHeadz display cases from iDisplayit. Luckily, we've got you covered:

• 4x LEGO BrickHeadz Display Case for LEGO BrickHeadz TMNT 40878
• 5x LEGO BrickHeadz Display Case for LEGO BrickHeadz Mandalorian 40856

Your Baby Grogu BrickHeadz and the Anzellan Droidsmith will have a little extra headroom, but they have the standard 6x6 studs base, just like the 8cm BrickHeadz.

Choose a black, white or clear base. Our LEGO BrickHeadz display cases are stackable when you go for the clear base option, giving you better visibility as your BrickHeadz display climbs towards the ceiling!

All our display boxes are shipped flat-packed and are easy to assemble using the supplied fixings and screws, so you can get your BrickHeadz on display without delay.
