She is Dana's shy, girly friend voiced by Kari Wahlgren in the voice she used for Suzy on Phineas and Ferb.
Sophie is the girly-girl to Dana's tomboy. This girl has a loyal personality, and is always willing to help Dana when she gets a bit out-of-control. She's also extremely stylish and knows all the latest trends!
She has blonde hair worn up in a high ponytail, purple eyes, and wears a shirt patterned just like the wrapper of the Choxie Dark Chocolate Mini Cookie Truffle chocolate bar, but in pink and purple instead of blue and green. Her pants are blue and green striped stockings and she wears dotted socks and windowpane checker shoes.
- She prefers calling the Dizzy kids not just by their first names, but by their full nicknames (e.g. She calls Dana "Dizzy Dana" and not just "Dana").
- Cotton candy is her favorite snack.
- She is 9 years old.
