The LEGO DREAMZzz Nightmare Shark Ship (Set 71469) is the flagship large set from the LEGO DREAMZzz Trials of the Dream Chasers theme, inspired by the LEGO DREAMZzz animated TV series. This 1,389-piece building set challenges builders aged 10 and up to construct a massive dream-world vehicle that can be assembled in two distinct ways: ship mode, featuring powerful engines and sails, or tank mode, complete with cool accessories and flying eyeballs. In either form, the finished model measures over 12.5 in. (31 cm) high, 23.5 in. (60 cm) long, and 10 in. (25 cm) wide.

The Nightmare Shark Ship is packed with interactive play features. The iconic shark jaw opens wide to place a minifigure inside, while a push-button mechanism reveals a secret hidden treasure chest. The rear cabin is fully removable, and the set includes a central cage with a trapdoor for dramatic storytelling moments. Swiveling turrets on both sides can be aimed and fired to add to the battle action. The story centers on the Nightmare King, who has captured Izzie's beloved Bunchu plushie and fused it with a pirate ship to create the fearsome monster vehicle that heroes Mateo and Izzie must reclaim.

The set includes 7 minifigures — Mateo, Izzie, Z-Blob, Nova, the Nightmare King, Susan, and Snivel — along with accessories including a Pencil Staff, Boomerang Sword, Nightmare King's Staff, and a Bunchu plushie figure. Story-led building instructions are included and are also available digitally in the LEGO Builder app.
