Fritz is a young skunk with dark grey fur. His inner-ear is pink, while he has a big white marking on his face and tail. His nose and eyes are black.
Fritz is a very smart and studious Skunk. He adores anything science related and has a huge imagination - which he often puts to good use whenever creativity is involved. Such as building space-related things he made up, or using some outside of the box methods in projects. His smarts are admired by the rest of the class, and he gets complimented fairly often, but when something doesn't work right he sometimes gets depressed until he gets encouraged to keep going. He used to be very messy and didn't think before trying to make something new, until he realizes how problematic this was.
He is very mature with his thought process, and is nice to the others. While he is the intellectual type, he also enjoys other activities and isn't shy - as his initial personality may lead one to think.
Normally Fritz wears a light yellow T-shirt with a gold collar and sleeve cuffs. Around his neck is a melon-colored tie, which he later trades for a green vest after he returns to the school after temporarily moving away.
He has also been seen in:
- A Magician hat and cape
- Swim wear
- Winter Clothing
Fritz is very kind to Lily, even when she forgets something. He is shown with her a lot of the time and is probably one of her closer friends, due to his kindness and understanding.
Fritz appears with Nora a fair amount of times, including the intro. When he isn't with Lily, chances are he is with her instead.
Fritz and Charles are shown to have some interests, such as building things and collecting rocks. They are not shown hanging out very often though.
Fritz and Timothy are shown to be good friends early on during the series, sharing various things with each other before anyone else.
