The LEGO Technic Monster Jam Monster Truck set includes a 2-in-1 pull-back action truck that can be rebuilt into a racing truck model. The design features the 'Fierce Pup' livery with color-accurate details and stickers to match the Monster Jam truck. Children can pull back the truck to launch it for races or to mimic stunts seen in Monster Jam events. The model can later be rebuilt into a racing truck for a different play experience. Designed for ages 7 and up, this off-road vehicle set introduces basic engineering and mechanics concepts for LEGO and Monster Jam enthusiasts.
