The following article contains an answer for the question: What is the name of the cat that causes Mammy to fall off of the chair? , can you please find it?   Tom is chasing Jerry around Mammy Two Shoes, while she is yelling out confusing instructions on where to chase Jerry. She has a broom ready to hit Jerry but instead she bungles things by clumsily hitting Tom on the head causing the cat to forget who he is and believing he is a mouse like Jerry, except he's rude. Tom terrorizes Two Shoes by shaking the chair, causing her to fall off it, before she quickly flees from the deranged cat. Jerry then overhears the terrified Two Shoes on the phone talking to a doctor about Tom. She hears from the Doctor that Tom is suffering from amnesia - a term she doesn't understand. Seeing Tom approaching her with mischief on his mind, Two Shoes has to cut her phone conversation short before she can find out more details about Tom's current illness. The hapless housemaid begs Tom to leave her alone and attempts to evade him by walking away on stilts. Tom mischievously pulls the stilts from under her, causing Two Shoes to fall down with an enormous crash, silencing her. The deranged feline then runs back into the mouse hole and break Jerry's bed, Jerry finds Tom even more annoying as a 'rodent' than as a cat, and so plots to bring him back.
