This may or may not matter to you, but I don't think Caillou is actually a name - it means pebble. Anyway, it's hell of a lot easier to pronounce than Pororo!! (my dd loves that show, but calls it 'la la la' because Pororo is so hard to say).
Nah doesn't matter to me - Mehkelti doesn't even have a meaning - at least Caillou does.. LOL
