Young explorers 8+ dive into a world of underground adventures with the LEGO Minecraft Pickaxe Mine (21277). Ore extraction, daring battles, and brick-built explosions await kids as they blast through rock walls with a TNT-loaded minecart, fight off a hostile spider jockey, and help Alex, a Miner, and their baby polar bear companion uncover hidden treasures. Perfect for gaming enthusiasts, this interactive LEGO Minecraft building toy lets young builders recreate their favorite video game adventures through hands-on creative play. Parents can help young ones continue the fun with additional Minecraft Lego sets (sold separately) and by accessing the LEGO Builder app, so kids can zoom in and rotate their model in 3D as they build.
