She is an orange otter with a snow white belly and long black hair. Her body shape resembles Jelly Otter's, but with a longer tail. Her eyes on the other hand, are shaped like Peanut Otter's and lack eyelashes. She originally had a small fish-shaped birthmark on the left side of her neck, but was removed in 2014.

She wears round glasses, a bright yellow and bow with 2 blue circles on the front and back, and brown Lake Hoohaw style (according to her profile)-Converse shoes.

Her sleepwear consists of hot pink footsie pajamas with a purple turtleneck collar, which even covers the tail. Whenever she has trouble sleeping, she puts on a purple sleeping mask.

On a few occasions, her hair is in a ponytail. For example, in Sophie the Otter: Tough Girl, she sports it in the secret levels where she slides down on her belly. The reason is that she wants to keep her hair neat.

In 1930's World of Sophie the Otter: Tough Girl, she becomes grayscale and she loses her glasses. She has pie-eyes and wears Mickey Mouse-esque gloves.

In the Supernanny: The Theory Animated episode "The Nuclear Age", she wears a blue headband and bow, black-framed cat eye glasses, a light pink and white plaid '50s style dress, and brown penny loafers.


She is a highly intelligent character with an IQ of a whopping 150 and is usually polite and helpful. Her feelings vary depending on the situation, ranging from peppy and innocent to furious and frustrated. She rarely believes in a tough approach because she is always helping children learn from their mistakes.
