The Wind in the Willows, the first half of Disney's 1949 animated feature film The Adventures of Ichabod and Mr. Toad, features Water Rat as a key character and buddy of Mole, Angus MacBadger, and J. Thaddeus Toad.
Ratty is presented as stuffy and refined in Disney's rendition, as opposed to his more casual and easygoing counterpart from the original book. In Mickey's Christmas Carol, he and Mole played alms collectors.
