Embark on a subterranean Minecraft journey with the LEGO Minecraft Underwater Adventure (21598-1) set, featuring 310 pieces for deep-sea exploration. This 2026 release transports players to the ocean depths, where Steve the deep-sea diver, armed with his sword and axe, navigates his boat through the waters. Accompanying Steve are a Dolphin and Tropical Fish, while a Drowned wields a trident, posing a threat amongst the coral reefs. The set recreates an Ocean Monument and an Ocean Ruin, concealing a buried treasure chest with gold and an emerald. Guardians and an Elder Guardian protect these aquatic domains, capable of firing projectile elements to thwart Steve's progress, adding action to the build. Steve's binoculars and map aid in charting the course through this block-built realm.
