Recreate the second task of the Triwizard Tournament from Harry Potter and the Goblet of Fire with this action-packed building set. The set features a buildable underwater scene with an arch ruin, 2 caves, and flexible LEGO elements that create the effect of 2 minifigures floating underwater. A buildable pier model includes a minifigure-diving function that can be placed on top of the underwater scene.

The set includes 5 LEGO minifigures: Harry Potter with flipper elements and dual-sided head showing gills from eating Gillyweed, Viktor Krum with a shark head element, Hermione Granger, Ron Weasley, and a Merperson with trident. Also included is a Grindylow figure, a small rowboat that fits one or two minifigures, and accessory elements such as Gillyweed potion, wand, kettle, mugs, and a printed clock tile.

The underwater section uses dark blue and sand green brick-textured pieces to create the Black Lake environment, with chains to secure the characters being rescued. Above water, the pier structure features sand green Asian-themed pieces, a table with accessories, a ladder, and a rotating clock mechanism. Contains 349 pieces and is recommended for ages 8 and up.
