LEGO's Description[] This is a description taken from Please do not modify it. (See an archive of the product’s page)

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!
  • Extend the drilling arm and pivot into position!
  • Includes 2 miner and 2 rock monster minifigures!
  • Measures over 9" (22cm) long and 6" (15cm) wide!
