You may just have miscounted, or perhaps there is a twist to the number. (Does it start with 0 or 1?) Anyway, try playing with a few other numbers - 58, 60 etc - till you get the one you want.
Or see if you can identify the fact you've got, and then work out which is the correct number for the face you want.
Or line up a whole row of loons, give them each a different face and see which is the one you want.
