When does Screwy Squirrel return?

Screwy Squirrel (also known as Screwball Squirrel) was created by Tex Avery for Metro-Goldwyn-Mayer. The character was known for being brash and erratic, with few sympathetic personality characteristics such as Bugs Bunny's nobility and Daffy Duck's pathos. The final cartoon in the series, Lonesome Lenny, ends with a scene indicating Screwy has been killed off as a regular MGM character.
