Woodstock is a fictional character in Charles M. Schulz's comic strip Peanuts. He is Snoopy's closest friend and, after Snoopy, the most recognized non-human in the strip. Woodstock quickly became Snoopy’s best friend. The only non-avian character who can understand Woodstock’s speech is Snoopy.
When depicted in the comic strip, his speech is rendered almost entirely in "chicken scratch" marks, with Snoopy either directly translating or allowing the reader to deduce Woodstock's meaning in the context of Snoopy's replies. Woodstock does make nonverbal noises such as yawns (November 23, 1972), laughter, sighs (November 22, 1972) and "Z"s or snores to indicate sleep. He also uses punctuation marks like "!" or "??" to indicate emotions.
