Goofy Goofy is a funny-animal cartoon character created in 1932 at Walt Disney Productions. Goofy is a tall, anthropomorphic dog with a Southern drawl, and typically wears a turtle neck and vest, with pants, shoes, white gloves, and a tall hat originally designed as a rumpled fedora. Goofy is a close friend of Mickey Mouse and Donald Duck and is one of Disney's most recognizable characters. He is normally characterized as extremely clumsy and dimwitted, yet this interpretation is not always definitive; occasionally Goofy is shown as intuitive, and clever, albeit in his own unique, eccentric way.
