Matchbox Mega Rig Dino Adventure
Recombine the older Matchbox rig into vehicles with different jobs, then build a short dinosaur encounter around one change.
The play at a glance
Change the vehicle to change its job
The Mega Rig Dino Adventure set is built around taking a large vehicle apart and combining its modules in new ways. The original image shows a long dinosaur transporter and a different tracked arrangement, with smaller vehicles and equipment alongside.
Give the first build one job. Then change a module and explain how the revised vehicle will approach the same adventure.
Start with a transporter
Use the matching guide to identify the chassis, cab and carrying section. Make one of its illustrated vehicle arrangements before inventing a variation. Check that the parts connect as intended and the vehicle can move without a loose section dragging underneath.
Choose a departure point and destination on a clear floor or tabletop. The mission might be moving equipment to a lookout or taking the dinosaur to an imaginary enclosure. Decide which part of the build makes that job possible.
Rebuild for a smaller journey
The G3714 diagrams show smaller wheeled combinations as well as the long rig. Pick a shorter arrangement and give it a different role: scout the route, bring a figure to the scene or carry a piece of equipment.
Compare the two builds. Which has more room for the imagined load? Which needs less space to turn in the scene? Keep the answer tied to what you can observe rather than treating every possible attachment as an equally useful vehicle.
Let the player supply the action
The guide shows a handle-operated winch and a capture-claw control. It also shows a lever on the dinosaur’s fitted collar opening the mouth. These are actions a player operates; the sound feature does not establish that the dinosaur walks by itself.
Choose one action to resolve the story, then pause. A delivery can finish when the vehicle reaches the enclosure; an encounter can finish when the explorers decide to return. The supplied capture scenario is one option, and a quiet observation expedition is another.
Reset the modules for another story
Separate only the connections intended to come apart and keep the figures and accessories together. Use the matching diagrams for the collar, cage and other unfamiliar fittings. If using the launcher, follow the guide, use only its intended projectiles and keep people and animals out of the firing direction.
An adult should handle the sound component’s button-cell compartment and make sure its cover closes securely before play. The next adventure can start by assigning a new job to an existing build rather than trying to reach a particular number of combinations.
The historical record
Original Toysit coverage
The original product paragraph, thirty-combination headline and complete dinosaur-play essay remain below. The broader claims about learning and development are historical commentary. The toy’s dinosaur encounter is imaginative play, not a reconstruction of real dinosaur behavior.
Megarig breaks into thirty vehicle combinations
This big Matchbox truck lets boys create their own adventure by transforming and constructing the truck into smaller vehicles and accessories to prepare to their mission of capturing a dinosaur. Kids combine and transform with over ten action pieces. The dinosaur stomps and chomps and roars for realistic adventure play action.

Reviewed October 15, 2026 against the original photograph and all four pages of Mattel’s G3714 instruction sheet. The cab, chassis, cage, small vehicles and dinosaur collar agree with the pictured design. The guide documents recombination, a hand-operated winch, capture claw and lever-operated dinosaur mouth, alongside a battery-powered sound component. It does not establish autonomous walking. No total of thirty builds was independently enumerated, and no physical set was tested.
