I can see we have generated some enthusiasim for finding your
very own 'rare peeps' within a family circle:)
Just remember the formulas:
Dad's head # plus Mom's head # = total. Divide that total by 2 and your children should be that number or within 5 of it, up or down the scale.
Heads are numbered from 1 [black] to 50 [Spike & Rainbow}
Easiest way to determine is to copy the head images to your computer and print out to number. Or, still copy and pull up whenever you are curious, numbering in your head at the time.
