Tom and Jerry Wiki

Nibbles "Tuffy" Mouse (also known as Tuffy Mouse) is a character from the Tom and Jerry cartoon series. He is the little grey, diaper-wearing orphan mouse whose cartoon debut came in the 1946 short The Milky Waif. Nibbles was later featured in the 1949 award-winning short The Little Orphan. Nibbles is wearing a diaper is due to the fact that he is portrayed as a young mouse.

Origin and Development

Nibbles' first actual appearance came in the 1942 comic book Our Gang Comics #1, where despite his diaper, he was presented as a peer of Jerry rather than a younger individual. In the comics, the grey mouse's name was given as Tuffy Mouse from the start. In the comics, Nibbles remained a peer of Jerry with no relatives. But in 1953, the animation writers decided to change his on-screen relationship to Jerry. He became Jerry's nephew in Life with Tom.

Nibbles always seems to deliver the final blow. In The Little Orphan, Nibbles shoots a wine bottle at Tom. in Touche, Pussy Cat! he cuts open a barrel with champagne in it and washes Tom away (he gets drunk in the process) and in The Two Mouseketeers, Nibbles fills a cannon with food and shoots it at Tom.

Nibbles was more often a speaking character than Jerry. In the "Mouseketeer" subseries, he spoke mostly in French, resorting to English whenever a slapstick humor depended on it. The only exception to this was Robin Hoodwinked where he talked purely in Æld English and had a different, rougher voice. Nibbles looked somewhat more mature in Robin Hoodwinked as well, despite the fact that he still wore his diaper. The Mouseketeer shorts almost always featured sequences in which Nibbles got drunk. In his last appearance in Robin Hoodwinked, he is also shown to be drunk as the cartoon comes to a close.

In the Tom and Jerry Tales episode Cat Nebula, Nibbles appeared as Jerry's sidekick and had a younger voice. Strangely, he spoke in a feminine French accent in the non-mouseketeer Tales shorts Cat Show Catastrophe and Cat of Prey. In Babysitting Blues, Nibbles was actually portrayed as a real baby who was at an age where a human baby couldn't crawl, though it is unknown if this was really Nibbles or another nephew of Jerry.


Nibbles has a fond taste for food, which can be a weakness as sometimes he forgets about escaping from foes and starts to search for his food.

In "The Two Mouseketeers," Nibbles makes a sandwich while singing "Alouette," which causes him to get caught by Monsieur Pussycat (Tom).
