Choco Puffles are Ruby Redfort's favourite breakfast cereal. It is introduced in Ruby Redfort, Look Into My Eyes where Ruby solves a puzzle where there are 5 pieces that when matched up correctly form a perfect square - and she did it in 6 and a half seconds! In Ruby Redfort, Take Your Last Breath, it was mentioned when Ruby was little, solves a problem puzzle on the back of the box, asks her dad to post it but he doesn't - the prize was a lifetime supply of Choco Puffles and it was made by Spectrum!
