Biography
She faked being a soothsayer to get money from the mice. She created the Manhattan monster to get rid of the rodents because when she ran away from her owner, the other dogs didn't want to be around a dog who looks similar to a rodent. She snapped and got cats to help her make a monster to wipe away all the rodents of New York. She lock them in crates and sell them to cats to be eaten. In the end Fievel knocks her out. At the end of the fight with the cats, Tiger and Tony catch Mousey from escaping into the sewer, and the dog council send her back to her owner. She claimed it was even worse than going to the city pound.

She despises Nellie for doubting the beliefs of the night monster and underestimating her. She gave Tony a fake clue to the night monster so Fievel and Nellie could go to an old house to be finished off.
