Can't find this at the moment but I seem to recall a Japanese designer commented on social media that Amy took design cues from Madonna.
Just as well,
>Amy was conceived shortly after Madonna was rejected and was in an internal SoJ "bible" that mangas picked up
>Madonna apparently had a very similar role in that her chasing after Sonic would get her in hijinks
>Naoto Ohshima designed both character concepts, and after the human was vetoed he brought the hedgehog in Sonic CD
