Nibbles

From Tom and Jerry Wiki

Nibbles is a small gray mouse adopted by Jerry at "Bid A Wee Mouse Home". At first Nibbles was just a very hungry and silent waif whose favorite drink was milk, which caused a lot of problems including Tom. A little later in the series, Nibbles developed French and British accents. He was one of the Mousketeers and one of Robin Hood's band together with Jerry.
