We can see that all Dalmatians have an uncountable amount of random spots all over their coats. Who would even bother counting them? But, to be precise, it was said that there are exactly 6,469,952 spots on the 101 Dalmatians’ dogs and puppies. So, 72 belong to Pongo, and 68 to Perdita, the rest belong to the puppies. They each have 32.
99*32+(72+68)=3,308. Totally unclear how you get to 6,5 milion with those numbers...
