Nibbles the Mouse

Lore & Background

Nibbles the Mouse is a recurring character in the Tom and Jerry franchise, first appearing in the 1940s. He is often depicted as a baby or toddler mouse, with a high-pitched voice and a playful, sometimes clumsy demeanor. Unlike Jerry, who is more cautious and strategic, Nibbles tends to act on impulse, often getting into scrapes that require Jerry's help. Despite his small size, he is brave and loyal, frequently joining Jerry in outsmarting Tom the cat.

In Their Own Story

The kitchen was quiet, save for the ticking of the clock and the soft hum of the refrigerator. Jerry was curled up in his hole, dreaming of cheese, when a frantic squeak shattered the peace. Nibbles tumbled in, head over heels, his fur dusted with flour and his eyes sparkling like Christmas lights. 'Jerry! Jerry! Tom has a new mousetrap—it's shiny and has a little flag!' he chirped, bouncing on his toes. Jerry groaned, rubbing his temples, but a small smile crept onto his face. He knew this meant another wild ride. Together, they crept out into the moonlit kitchen, Nibbles clinging to Jerry's tail like a tiny tugboat. The trap snapped with a metallic clang, but instead of catching a mouse, it snagged Tom's tail—Nibbles had tied it there with a ribbon while Tom wasn't looking. Tom yowled, leaping into the air like a rocket, while the two mice scurried to safety, their giggles echoing through the house like wind chimes in a storm.
