Brick Fanatics
“Drawing inspiration from The Goblet of Fire, this set recreates the second task of the Triwizard Tournament. A chunk of underwater scenery (and a malevolent mermaid) are included, as are amphibious versions of Harry Potter and Viktor Krum.”

Brickset
“76420 Triwizard Tournament: The Black Lake contains everything I was hoping it would, which is no easy feat, given the expectation for a location LEGO has not produced since 2005! I think the vertical configuration looks nice and the transition between above water and... More underwater settings is exemplary, other than the superfluous rowing boat.”
