Monster Jam 1:64 Dirt Squad Vehicle Assortment. Prepare the arena with a Monster Jam Dirt Squad vehicle. These 1:64 construction-themed machines combine creature styling with working parts that help children imagine building jumps, shaping a course and clearing the arena after a run. A tail hook adds towing play with compatible small trucks. The range brings the hard-working behind-the-scenes side of Monster Jam into a vehicle collection, offering another role beyond the main monster-truck performance. One individual retail item or pack is supplied. Designs vary and images may show possible versions; a specific design cannot be guaranteed.
