These characters are in the 1992 manga. I could be mistaken, but isn't the dad labelled ポリー ? Which would be "Polly", but I think the consensus is that "Paulie" was the intention. At least some issues of the manga spelled it ポーリー , but they weren't always super consistent with name spellings. Paulie, Brenda and Tania have their relations (father, mother and sister) in brackets next to their names, but the boy, Nicky/Nikki ( ニッキ ) doesn't have anything next to his name. Unless I've missed something somewhere? In the manga, Nicky is Sonic's younger alter-ego. Whenever there's trouble, Nicky unknowingly transforms into his older self, Sonic. The other notes seem to just be about colors. The note under Brenda's name, pointing towards Brenda and Tania seems to say "oudo daidai" - which is "yellow ochre orange", apparently. Amy's shoes are "sumire-iro", violet color.
