This Intense Gorilla Fight Left Zoo Visitors a Bit Rattled

A little boy had a close encounter with lion at a zoo in Japan.

A video posted to YouTube shows the two-year-old boy staring at a male lion during a visit to the Chiba Zoological Park with his family.

When the toddler turns his back, the big cat springs up and rushes at him, only to slam into the glass wall of the enclosure.

The startled boy stumbles back when the massive animal rams into the glass.

Zookeepers said the lion, which weighs 400 pounds, gets excited around small children and just wanted to play.
