Buttermilk Sky, a Nigerian dwarf goat kid, has taken to leapfrogging over friends at a farm in Maine, USA.

The five-week-old lives at the aptly named Took a Leap Farm in Houlton.

In footage posted on YouTube last week, the little goat shows its mischievous side appearing to deliberately knock over its friends - they do not seem to mind though.

The video has nearly two million hits online.
