He sees you when you're sleeping; he knows when you're awake ...
He knows if you've been bad or good.
Does anyone else have the problem of never having enough ice score tokens to go around? In our first game we just cashed them in for larger denominations before we noticed that the physical quantity of them was important.
This is why the (admittedly confusing) rule about using the square tokens in final scoring is there - if there aren't enough ice tokens to use for scoring, use the square resource marker instead. The square marker counts as three tokens of the appropriate resource.
