Tom Thumb in Trouble, a 1940 Chuck Jones directed short film is, according to Jerry Beck and Will Friedwald, "…a deliberate, last time effort [by the Warner Cartoon staff] to figure out the Disney formula.  Disney would be used only as a source of satire in the future."*  This model sheet of the bird character (that saves Tom Thumb not once, but twice) was created by Chuck Jones.
