While under Disney's creative control, Oswald was one of the first cartoon characters that had personality. As outlined by Walt himself: "Hereafter we will aim to Oswald a younger character, peppy, alert, saucy and venturesome, keeping him also neat and trim." With Oswald, Disney began to explore the concept of "personality animation", in which cartoon characters were defined as individuals through their movements, mannerisms and acting, instead of simply through their design. Around this period, Disney had expressed, "I want the characters to be somebody. I don't want them just to be a drawing." Not only were gags used, but his humor differed in terms of what he used to make people laugh. He presented physical humor, used situations to his advantage, presented situational humor in general and frustration comedy best shown in the cartoon "The Mechanical Cow". He would make use of animal limbs to solve problems and even use his own limbs as props and gags. He could be squished as if he was made of rubber and could turn anything into tools. His distinct personality was inspired by Douglas Fairbanks for his courageous and adventurous attitude as seen in the cartoon short "Oh, What a Knight".
