About Sally Acorn
Sally Acorn began as the name given to the small squirrels freed in Sonic the Hedgehog in English speaking countries, the same animal was known as 'Ricky' in Japan and was, as it's name implies, a he rather than a she. For the west she was given a bow for promotinal art, but the animal's in-game sprites were left the same. This is the version of Sally Acorn used in Fleetways' Sonic the Comic series in the few times she featured.
Princess Sally Acorn, the version of the character most will be familar with, was developed and created by DiC for thier Sonic the Hedgehog cartoon, know coloquially as Sonic SatAM. Designs erroneously shown in Sonic the Comic show that originally she was designed as a pretty and smart ground squirrel, a princess, with long blonde hair and wearing a red dress, however, this design was never used. Sally's final design is that of a small, slender brown ground squirrel with brown to red hair wearing blue boots and (later) a blue vest.
Initially, however, she was pink, and this design was used in Adventures of Sonic the Hedgehog where she was protrayed as a spoilt princess demanding presents, and early on in Archie Comics where the character made her debut (this was later explained away in continuity as being the result of her falling into a vat of chemicals). Though her image was the most mercurial of the DiC/Archie designs at the beginning, it remains the least altered since, with longer hair, that has since been trimmed back to her original look, being the only change in her appearance. Sally has made only one appearance in the Sega video games, a cameo in a bonus level of Sonic Spinball, where she appeared in her pink form.
