Question: What kind of animal is Jerry Title: The Milky Waif Movie plot: Jerry is asleep in his bed having a nightmare when he wakes to the sound of a knock at his door and goes out to open it, finding a basket on his door step. He pokes the basket, and it comes alive and runs around in circles. Jerry pulls the blanket off to reveal Nibbles. An attached note says, "Please take care of Little NibblesHe's always hungry! P.S. Feed him lots of milk." Nibbles then begins licking his lips and rubbing his belly. Seeing that he has no food, Jerry tiptoes out of his hole, spotting Tom asleep by his bowl of milk. Nibbles sees the milk and runs toward it, but Jerry pulls him back and goes out to get the milk for him. Nibbles runs out, accidentally waking Tom. Jerry grabs Nibbles and the two fall into the bowl of milk, splashing it in Tom's face and waking him. Tom, startled, looks around and sees no one, so he starts to drink his milk. Jerry and Nibbles are under the milk holding their breath until Tom unsuspectingly scoops up Nibbles with his tongue. Jerry jumps out of the milk and opens the cat's mouth to retrieve Nibbles, which begins the chase. The mice retreat into the mousehole before Tom crashes headfirst into the wall. Jerry builds a pipeline of straws to the milk but Tom turns the tables by grabbing the end of the straw and sucking Nibbles through it. Jerry squishes the end of the straw, saving Nibbles just in time, and blows the small mouse into the mousehole. Tom chases Jerry back to his hole but the cat moves the hole over so that Jerry crashes into the wall. Tom grabs Jerry, but Nibbles comes out and hits Tom's tail with a hammer. The chase starts up again until Nibbles sips and spits some milk into Tom's face. Jerry and Nibbles hide in a closet, while Tom pounds on the door. Jerry uses a container of shoe polish to disguise himself and Nibbles as a pair of black people.

However, the disguise is...
