Screwball Squirrel, alias Screwy Squirrel, is a cartoon squirrel created by Tex Avery in 1944, and first appeared in Screwball Squirrel.
Screwball Squirrel was created for MGM by Tex Avery to recreate his success with Bugs Bunny and Daffy Duck when he worked with Warner Bros.. Although Screwball's career was short-lived, he certainly lived up to his expectations.
Debuting on April Fool's Day 1944, Screwball's all-too-brief career lasted for only five cartoons between 1944 and 1946, but all five cartoons remain popular today despite the minimal number.
In his "final" cartoon, Lonesome Lenny (1946), Screwball is apparently killed off by his antagonist, and is not used by Avery again for the rest of his lifetime.
During the 1960's, Screwball appeared in Our Gang Comics (an imprint of Dell Comics), and creditted as Skrewy the Skrewball Squirrel, and was briefly mentioned in Who Framed Roger Rabbit, but it wasn't until the 1990's that Screwball would be revived for TV, as a backup feature to Droopy, Master Detective.
On April 1st 1997, Cartoon Network staged a supposed takeover by Screwball, who attempted to make April Fool's Day a national holiday, and his second cartoon Happy Go Nutty was played for twelve hours over and over..
Since then, Screwball has only been seen in idents for the Boomerang channel, cracking walnuts on his head and declaring: "There's more after this!".
