Roger also starred in a comic book series published by Disney Comics from April 1990 to September 1991 and a spin-off series called Roger Rabbit's Toontown, published from June to October 1991, which featured Roger in the first story and supporting characters like Jessica Rabbit, Baby Herman, Benny the Cab, and the Toon Patrol. The series continues the adventures of Roger Rabbit, who has since returned to working for Maroon Cartoons, now under C. B. Maroon. The comics were usually split into two stories, with one main feature focusing on Roger's adventures, and a back-up feature presented to look like an actual animated subject. While Jessica Rabbit, Baby Herman and Benny the Cab all appeared in the stories, Eddie Valiant was seldom seen, replaced by a new detective character named Rick Flint. This was given an in-universe explanation in the first issue: Roger had a new case for he and Valiant to team up on, but Valiant told Roger he wouldn't be able to help him, as a result of his heavy workload. So to not leave Roger on his own, Valiant referred him to a "new kid" private detective, Rick Flint. The editorial reason for omitting Valiant from the comic was not having the likeness rights to Bob Hoskins outside of the first issue. Other new characters introduced were Lenny, a toon plane who was Benny's cousin, and Mel, who was Roger's sentient mailbox. The series had a one-off 3D strip as part of the "Disney's Comics in 3-D" series, which reprinted the back-up features of earlier comics and converted them into 3D. The Roger Rabbit comic book line lasted 18 issues, ending at the time of the Disney Comics implosion. However, new stories involving Roger and company continued to appear in the pages of Disney Adventures until after the May 1993 issue.
