It's no secret boys love their toys and the Transformers are probably one of the favorites on the list.

The gigantic creation you're about to see might even astonish the most serious cartoon enthusiasts.

11.5 meters tall and 6 tons in weight. This huge transformer is being put up at the north square of Beijing's Bird Nest. And believe or not, it is all made of old auto parts.

Countless tires, steel plates, and hubs, it takes five trucks to transport the jumbo's components to the site. Assembling the two legs alone costs over two hours.

As one of the promo activities of the Green Dream Park, it showcases an example for the theme of Green Innovation, Green Fashion and Green Life that the Dream Park firmly supports.
