No woozle illustrations appear in A. A. Milne's original stories, but it is often assumed that a woozle is something like a weasel, and they are depicted as such in the characters' imaginations during Winnie the Pooh and the Blustery Day, included in The Many Adventures of Winnie the Pooh, as well as physically in the television series The New Adventures of Winnie the Pooh.
According to Pooh, Woozles frequently travel with Wizzles. Woozles are first mentioned in a Pooh storybook when Pooh Bear and Piglet attempt to capture a "Woozle", but it is later revealed that the two woozles and two wizzles were really the footprints made in the snow by the duo, an error pointed out by Christopher Robin as he watches the two go round and round the larch spinney at least five times.
In the television series, they are enemies of Pooh and his friends, are known for stealing honey, and are often associated with heffalumps. One particular woozle featured on the series was a villain called Stan. His sidekick was a dim-witted heffalump called Heff.
Ventriloquist Jeff Dunham's puppet named Peanut is described as a woozle, a mammal native to Micronesia, although Peanut bears little to no resemblance to Winnie the Pooh's woozles. Mystery Science Theater 3000 fans have noticed Jeff's line being used on MST3K: "He's a woozle, and his name is Peanut."
The original name for the fraggle in Fraggle Rock was Woozle in the first draft of the series, according to the insert booklet on the Season 1 DVD.
"Woozle" is also a slang term for a ferret.
