My Epic Toy Monster Truck

I come from a different planet.
I feel warm but cold, smooth and awesome like a race track.
I taste like rotten egg shell.
I have lots of scratches.
I can turn into an alien but I'm a monster truck.
I may be as old as god.
I am green and black.
I am a smaller version of a grave digger.
I can flip.
I can do lots of stunts.
I can be used indoor and outdoor.
I am older than Leonardo da Vinci.
I am small but epic.
One day I want to be a real monster truck.
