The Milky Waif
Jerry is awakened from a nightmare by a knock on the door: someone has left a foundling in a walnut shell with a note, giving his name as Nibbles and saying he needs lots of milk. Fortunately, there’s a dish handy, but it’s next to Tom. Nibbles scurries out and dives off Tom’s nose, then grabs a whisker for balance, waking Tom up. Jerry grabs him just in time and they hide under the milk. Tom laps up some milk and gets Nibbles; Jerry rescues him, and they run for the hole. Next, they try a very long straw; Tom catches them and sucks Nibbles through the straw. Much chasing follows, with a pause now and then for some milk. Tom traps Jerry in a milk bottle and chases Nibbles a while; he finally corners Nibbles and spanks him with a flyswatter. Jerry is so enraged he burst out of the milk bottle and lets out a ferocious roar; he grabs Tom by the tail and thoroughly pummels him, then stands over him as Tom feeds Nibbles milk.
The first appearance of Nibbles, the orphan mouse later known as Tuffy, who became the best supporting character the series ever had. He arrives here as a foundling in a walnut shell and immediately establishes the trait that defines him: an appetite entirely disconnected from any sense of danger.
Includes a soot-covered disguise gag typical of 1940s animation.
