The LEGO Technic Monster Jam Monster Truck set includes a 2-in-1 pull-back action vehicle that can be rebuilt into a racing truck model. The design features the signature 'Fierce Pup' styling with accurate colors and sticker details matching the Monster Jam truck. The pull-back mechanism allows kids to launch the truck for races or to perform stunt jumps inspired by Monster Jam events. The model can later be rebuilt into a different racing truck configuration for extended play. This off-road vehicle set introduces basic engineering and mechanics concepts, designed for LEGO and Monster Jam fans ages 7 and up. The set measures over 3 inches high, 7 inches long, and 4 inches wide when built as the Monster Mutt Dalmatian truck.
