Most foxes have one tail. Miles "Tails" Prower has two tails. From there, it seems to jump straight to nine? Where are all the 3-8 tailed foxes?
@matt tthey're too busy grinding for their eventual 9th tail to come out.
@Nine I see, most foxes are too embarrassed to be seen until they have their full set of tails. That's what makes Tails special, he accepts himself for who he is and the self-confidence gives him super speed
@matt and this is why Tails is the goodest fox
