Wally Walrus, another character in the Walter Lantz stable, was a comic foil for Woody Woodpecker in that character’s early cartoons, starting in 1944. Typical of the type, he was dim-witted with a short fuse.
Space Mouse was an odd addition to the Walter Lantz roster. Western Publishing, the comic book publisher that licensed the rights to publish comics based on the Walter Lantz properties, wanted to widen their line of Lantz titles, but didn’t see anything suitable after Woody Woodpecker and a couple others among the studio’s cartoon library.
The animated comedy team of Heckle and Jeckle was another Terrytoons production. Created in 1946 for the theatrical cartoon, ‘The Talking Magpies,’ they continued in that format and, later, on television in the programs CBS Cartoon Theatre, The Heckle and Jeckle Cartoon Show, and The New Adventures of Mighty Mouse and Heckle and Jeckle.
