LEGO Technic 42200 Monster Jam ThunderROARus Pull-Back

LEGO Technic set 42200, Monster Jam ThunderROARus Pull-Back, represents a dinosaur-themed Monster Jam truck with a pull-back function.

This model brings the Monster Jam ThunderROARus into the LEGO Technic range. The subject is a show truck with dinosaur styling, placed among the Monster Jam pull-back vehicles where a compact build and an action feature are more important than a realistic road vehicle layout.

Bodywork pieces and any decoration are used to suggest the distinctive ThunderROARus look, rather than to create a detailed scale model of a conventional truck.

The set suits builders who want a playable Technic vehicle or an addition to a Monster Jam line-up. It can be displayed as a themed truck, but its main role is launch-and-roll play. Within Technic, it belongs with accessible action models built around a straightforward mechanical function.
