The only actual numbers in ch.1 that I can find (excluding once, first etc..) start with 'one' in the 4th paragraph "the most beautiful one" then there are 'two' & 'three' in the last line of the second to last paragraph on p.17 in "two-or-three-bounce landing" and last is 'four' on p.18 second line from the top , "his four feet and tail"

Having the numbers in order seems like more than just coincidence, but, like every other lead, I have no idea where to go now.
