Hilarious Video: Toddler Spots Dinosaur In Woods - And Runs Like Mad!

When little Zack wandered into the woods, he got a VERY big surprise – in the shape of a terrifyingly real Tyrannosaurus Rex.

And the curious two year-old did what any sensible toddler would do – he ran like hell to get away from it!

The hilarious footage of the moment has been seen by more than half a million viewers on You Tube.

Little Zack stands stunned as he spies the animatronic dinosaur at a theme park in Texas, USA.

The clever lad informs his mum that the creature stood just 50ft away is a T-Rex.

But when the giant robot roars at them, Zack turns on his heels and disappears into the distance shouting: "Run, run."
