Wow, I have no idea. For a moment I thought possibly Irish, but it isn't. The YouTube video is from something called the "AppuSeries" which has an elephant icon, and Google tells me that "Appu" was the elephant mascot of the the 1982 Asian Games held in Delhi, so Indian sounds like a possibility.
To my U.S.-native ears it is a fairly strong accent, and not one that is well-known in the U.S.--or at least not to me.
