Snoopy
Snoopy is a loyal, innocent, imaginative and good-natured beagle who is prone to imagining fantasy lives, including being an author, a college student known as "Joe Cool" and a World War I Royal Flying Corps ace. He is perhaps best known in this last alternate persona, wearing an aviator's helmet and goggles and a scarf while carrying a swagger stick.
Snoopy can be selfish and/or lazy at times, and had his share of moments where he is mocking his owner, Charlie Brown, but through it all, he has shown great love, care, and loyalty for his owner (even though he can't even remember his name and always refers to him as "The Round-Headed Kid").
All of his fantasies have a similar formula: Snoopy pretends to be something, usually "world famous", and fails. His short "novels" are never published, and his Sopwith Camel is consistently shot down by his imaginary enemy, the Red Baron. Schulz said of Snoopy's character in a 1997 interview: "He has to retreat into his fanciful world in order to survive. Otherwise, he leads kind of a dull, miserable life. I don't envy dogs the lives they have to live."[3]
Snoopy imagines himself to speak, but never actually does; much like with real life animals, the human characters are unaware of his musings. Though very rarely, he talks, but usually to himself. His (very articulate) thoughts are shown in thought balloons. In the animated Peanuts films and television specials, Snoopy's thoughts are not verbalized; his moods are instead conveyed through growls, sobs, laughter, and monosyllabic utterances such as "bleah" or "hey" as well as through pantomime. The only exceptions are in the animated adaptions of the musicals You're a Good Man, Charlie Brown and Snoopy!!! The Musical in which Snoopy's thoughts are verbalized by Robert Towers and Cameron Clarke respectively. (His dialogue, however, is not "heard" by the other characters except Woodstock and other non-human characters.)
Snoopy's doghouse defies physics and is shown to be bigger on the inside than the outside. It is also his "airplane" in his fantasies. In the 90s comic strips, he is obsessed with cookies.
