8961 Crystal Sweeper is a set that was released in January2009 as part of the LEGOPower Miners line (being set number 6 in the series). Included are Rex, Brains, one Meltrox monster, and one Glaciator monster Minifigures. The set features a working harvester wheel, which can collect crystals and transfer them into a trailer at the back.
Grab every crystal before the rock monsters do!
Hungry rock monsters are on the loose, gobbling up crystals and causing havoc underground. Unleash the Crystal Sweeper and get them first! This massive mining vehicle spins its auto-rotating harvester wheel to collect a huge cargo of crystals and drop them into its rear-mounted bucket. Use the side-mounted laser crane to drill through rock, or deploy the motorcycle and ramp for emergency escapes and rescues. Just watch out for the monsters and their double-launching catapult!
Roll the vehicle to activate the rotating harvester and scoop up the crystals into the bucket!
