Set in a Minecraft desert outpost, kids role-play being a Cactus Knight, with its diamond armor and shield and sword. When 3 illager figures arrive to steal treasure, kids must defend the outpost. The set includes missiles that kids can launch with a flick of their finger, a variety of weapons and a barrel that holds the treasure. For extra digital fun, the LEGO Builder app lets kids zoom in and rotate models in 3D using their device.
