Trivia
- Besides the Sorcerer, the rat has never interacted with any other character in the series so far.
- The rat has only been outside the Sorcerer's Prison twice, he's about to eat the cookie and then see Randy as he fall down the stairs which he scurrying away in "Last Stall on the Left", and taking a gravy fry from the cafeteria while in a vent in "Bash Johnson: 11th Grade Ninja".
- The rat's squeaks are made by Dee Bradley Baker, who has voiced many animal voices, like Perry the Platypus from Phineas and Ferb, Waddles from Gravity Falls, and Appa and Momo from Avatar: The Last Airbender.
- The only instance the Rat was seen helping the Sorcerer stank people is in "McNinja - Brought to You by McFist".
- It is unknown what happened to the Rat after the Sorcerer was defeated, but presumably it has been spared by the Ninja, who is unaware of its relationship with the Sorcerer.
