Zecar came in to this world for a very important mission, other than to entertain us. All of the proceeds from the royalties will go towards reforestation projects in Rio de Janeiro State, Brazil. The funds will contribute to the planting of thousands of trees a year to help restore part of the Atlantic Tropical Rainforest, the most critically damaged in Brazil, with the richest variety of trees of anywhere in the world. To push Zecar, hold the front and the rear ends, not the sides, and gently give his wheels a spin by dragging them on a surface. Zecar has lots of torque, and he moves rather slowly. You can choose to have the traction be the front, or the rear wheels. You can also slide him upside-down on his flywheel and two free spinning wheels. Zecar is not a race car, nor a demolition derby machine. He should not fall off tables, nor should he be slammed around.
