Mandock - found googling
The Tinga Tinga House, Instyle Corp.
Mandock literally means frog in Indian. This names comes from the fact that the sound produced by the instrument resembles the croaking of a frog. It is used at festivals to get people into a festive spirit.
Performance
Holding the handle and swinging the body round causes sound waves to be produced which echo off the skin thus producing a loud sound.
Placing a finger on the body while swinging it, shaking the handle from side to side, opening and closing the fingers on the hand holding the handle can all produce different sounds.
When the sound produced falls in quality, you should apply more pine oil to the axle.
..so it is some form of musical instrument
