The story is based around six teenage Ninjas who use their fictional martial art fighting style of Spinjitzu to defend their land of NINJAGO from evil and ensure peace reigns.

Set details

Released in 2021, LEGO set 71755, Temple of the Endless Sea enables builders to recreate the story or indulge in their own fantasy adventures. 

With 1,060 pieces and measuring 26 cm high, 11 cm long and 57 cm wide this set is a great size, the eye catching gold, teal and black colour scheme also makes it a great display piece. 

Seven Minifigures consisting of Scuba Kai, NRG Nya, Glutinous, Prince Kalmaar, Prince Benthomaar and 2 Maaray Guards can be used to role play story lines as the Ninjas interact amongst the elements of the under-sea world including a laboratory, a prison, a submarine, a manta ray and the sea serpent Wojira in chains, all of which can be joined together in any order.

NINJAGO fans will be quick to realise this is the only set to also include both of the Amulets of Wojira and LEGO fans will also be pleased to find that there are plenty of rare building elements to be found in the set, either as recolours or returning and rare pieces.

Investment Potential

NINJAGO sets tend to have one of the shorter shelf lives at retail sale of all LEGO themes, with most sets being on sale for between a year and eighteen months. Based on this we would expect this set may well be retired early in 2023. Its currently in stock and available at the LEGO store for £99.99.

There seems to be little stock of it anywhere else so don’t hesitate in purchasing if interested as it may be soon retired and out of stock everywhere.

Theme Analysis

There are 32 sub-themes within the NINJAGO Theme, with nearly 500 sets produced in total since launched in 2011, producing average annual growth of 7%.

Some examples of the NINJAGO theme:

Set Number Set Name Retired Date RRP Current Value Total Growth Annualised Growth
2521 Lightning Dragon Battle November 2011 £62 £246 297% 13%

Comparable Set Analysis

The seabound sub theme consists of just 5 sets, all launched in 2021 and all still currently available at retail sale. This set is currently the third highest owned of the 5, with the highest owned being 71754 Water Dragon. This makes looking at comparable sets harder, so we have looked at the most comparable sets within the NINJAGO theme:

Set Number Set Name Retired Date RRP Current Value Total Growth Annualised Growth
2505 Garmadon’s Dark fortress November 2011 £50 £265 430% 16%
70728 Battle for Ninjago City August 2015 £90 £186 107% 10%
70751 Temple of Airjitzu March 2017 £170 £338 99% 13%
70670 Monastery of Spinjitsu November 2020 £80 £104 30% 14%


With no retired sets in the sub-theme we have been quite conservative in our projections for this set post-retirement having used some sets within the general NINJAGO theme. Having looked at the higher priced Temple like sets we do get some higher returns on retired sets and this does lead us towards recommending this set for investment purposes. Now would be a great time to purchase within stock in very short supply and retirement imminent.
