As Walt had to came up with the idea of a new character with his chief animator Ub Iwerks before Iweks received the letter from Disney.

Since Dinsey designed an idea of a mouse by attempting to use a name Mortimer,but the time his wife Lily came up with the idea the name Mickey.And so the star was later born.As Iwerk animated two Mickey Mouse cartoon which were used from his first idea inspired by Oswald the Lucky Rabbit.By later replacing Oswald the Lucky Rabbit. When Walt decided that his studio should make the first sound cartoon. Which the studio poured all the resource into the third making of the mickey mouse cartoon. That later Mickey Mouse became a sensation hit around the world.Which helped the financial success from the basis of the Disney's empire.As it remain to be mickey that became the studio icon logo.
