After the Alice Comedies, Disney's second animated series (after the Laugh-o-Grams) folded in 1927, Carl Laemmle approached Disney and requested a new, all-animated series featuring a rabbit. Disney and Ub Iwerks created a new character entitled "Oswald the Lucky Rabbit". The first Oswald cartoon, Poor Papa, was poorly received by Charles Mintz and demanded a better, younger version of Oswald. The next cartoon, Trolley Troubles, was well received, and the series officially launched.
