Fritz is a young skunk with dark grey fur and a big white marking on his face and tail. The inside of his ears are pink, and his nose is black.
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 & cape, swim wear, pajamas, and Winter clothing.
Fritz is a very smart and studious skunk who is very fond of science and is another one of Timothy Raccoon's best friends. 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.
- In Timothy Goes to School, Fritz leaves for another school in the episode "Fritz on the Move", but returns soon after in "Many Happy Returns" after his mother got a new job.
- Fritz, along with his other classmates, will make an appearance as an NPC in ToonWorld All-Stars Online.
