 In the instruction manual for the US version, Amy Rose is referred  to as "Princess Sally". This was probably intended to tie in with  the newly released cartoon "Sonic the Hedgehog" (1993) and the  comics, although being that the character of Sally was already  established, the only thing it achieved was to shove Amy out of the  potential cast completely. However, she did become part of the  supporting cast in the comics years later.
