If one day, travelling through the southern India, your car suddenly breaks in the middle of nowhere, far from big cities, and there will be a small village nearby, then, just in case, show the kids in that village this picture and ask them who this guy is.
If they recognise him and say: ‘This is Tux’, then you know that Vlad is somewhere here.
I didn’t teach them about Tux. I just mentioned his name a couple of times but today one girl told my wife that she knows this penguin. ‘His name is Tux’, she said.
