Princess Sally Acorn, daughter of King Maximillian Acorn, is quite possibly the most well known and prominent characters in non-canonical Sonic history, and is well known for being Sonic's first "official" love interest. Her earlier incarnations presented her as a snarky yellow cat/squirrel thing(seen above) and later as a pink-furred chipmunk(and later again confused from with Amy in the Sonic CD manual). Howver the true Sally herself has always been seen as a brown chipmunk gal with some awesome blue boots. Differring between continuities of cartoon and comics, Sally has always been portrayed as the princess of a kingdom under oppression by Dr. Robotnik, and a prominent member of the Freedom Fighters to defeat the menace and his evil roboticizing ways. Together with Sonic and many other fuzzy friends, she resides in Knothole Village and remains locked in an endless struggle to rescue her father, the King, from the fatman. While she doesn't possess much fighting skill/strength, she is incredibly smart and uses a special multi-purpose handheld computer named "Nicole" to support Sonic and crew in missions. She's also the only female Sonic character brave enough to walk around near-naked. Awesome.
