03Above-water viewing platform is substantially scaled-down relative to the movie
04Interior of top tower is very cramped, leaving little space for minifigures

What reviewers are saying

"4762 Rescue from the Merpeople was released in 2005, portraying the memorable second task of the Triwizard Tournament. These underwater ruins reappear in the excellent 76420 Triwizard Tournament: The Black Lake"

Brickset Reviews

"76420 Triwizard Tournament: The Black Lake revisits a scene last featured in 4762 Rescue from the Merspeople and its selection of minifigures is undoubtedly an interesting aspect of the model"

Ecosystem

4762 Rescue from the Merpeople — The 76420 closely resembles its 2005 precursor with similar minifigure selection and proportions, but includes an above-water structure on top. The archway remains from the original design and the colour combination of green and blue is familiar, though the new set uses teal, sand green and dark blue instead of brighter shades. The rowing boat directly originates from 4762 as a fun reference, though not conveniently integrated with the model. The original recreation of the scene was impressive, so the modern counterpart delivers good results, though modernized with new elements like the Grindylow and updated minifigure designs.

4762 Rescue from the Merspeople — The Black Lake revisits the same scene from the earlier set; minifigure selection is called out as more interesting in the newer version

Value drivers

Brickset Reviews: The Grindylow (first-ever LEGO appearance), exclusive versions of Harry with Gillyweed effects and unique gills, Viktor Krum with shark head, and the sand green Merperson with unique hair element are all value drivers

Exclusivity

Brickset Reviews: LEGO Harry Potter theme-specific set with all five minifigures exclusive to this set

Resale

Brickset Reviews: Strong aftermarket demand expected due to exclusive minifigures and Grindylow novelty; part-out value notably high for rare minifigures and specialty pieces

Standout parts (per reviewers)

Sand green 3x3 double concave slopesValue
New in this colour; used for the roof of the clock tower
Mermaid wavy hair component in medium nougat
Introduced with Candy Mermaid (43102 VIDIYO) but never before appeared in a traditional hair colour like medium nougat; creates texture as though the Merperson's hair is billowing underwater
Grindylow minifigureValue
Completely new minifigure type never before produced in LEGO; includes intricate tentacles and arms similar to Baby Groot parts; trans-opalescent brown colour with glittery finish
Shark head with teethValue
Component designed for Shark Suit Guy from 71011 Collectable Minifigures Series 15; repurposed for Viktor Krum's alternate head; teeth appear menacing though printed mouth does not completely fill space between them
Flexible rods
Used to keep chains taut for Ron and Hermione minifigures as though they would float to the surface; minifigures bob up and down when bumped; dark colour is easily overlooked among plants and animals
Pearl gold plates
Used around clock tower, creating attractive details
