The cartoon shows how the character, as the pleasant, friendly, and
good-natured "Mr. Walker" who "wouldn't hurt a fly nor step on an
ant", undergoes a change in personality to the violent "Mr. Wheeler"
when he gets behind the wheel of his yellow car. As Mr. Walker he's
polite, safe, and good-natured while as Mr. Wheeler; he is very mean,
reckless, and predatory.
Mr Walker/Wheeler- Goofy.
