Scarlett first appeared in 'Doggie Dash' as a main character. Her pet cat Wendy and Walter's pet dog, Rocky fell in love with each other, so they planed to play cupid with their owners. Over time during their pet spa career, Scarlett and Walter developed feelings for each other and by the end of the game got married.
Scarlett never appeared in the the 'Avenue Flo' games (possibly because Cassie Fisher was already a female character for pet themed jobs.) however, she was mentioned by Walter. This left some Diner Dash fans wondering about her whereabouts at that time.
She made her next main appearance in the moblie game 'DinerTown Pets', selling animals at the pet store and keeping them happy.
Scarlett often wears a blue business suit in the comic cut scenes and while she was working at the pet spa she wears a green t-shirt with blue jeans.
She has somewhat of a business woman personality in contrast to Walter's hippie personality but like Walter is loving with the pets and takes care of them and wants them to be happy.
