Three animated episodes adapted from what is widely considered to be the greatest comic strip of all time. In 'It's A Mystery, Charlie Brown' (1974) Sally is desperate for something to use for a subject in her science project, while at the same time, Snoopy has to play detective when Woodstock's nest disappears. In 'He's Your Dog, Charlie Brown (1968), the gang have had enough of Snoopy's pranks so they pressure Charlie Brown to act. He decides to send Snoopy back to his puppy farm for obedience training, but Snoopy is less than enthusiastic. 'It's An Adventure, Charlie Brown' (1980) is an anthology of stories directly adopted from the Peanuts strip. These include Charlie Brown having strange visions and rashes of baseballs and becoming the admired summer camp president known only as 'Sack' for the grocery bag he wears as a result. In another tale, Charlie Brown runs away to escape prosecution for literally biting his hated kite-eating tree. Also Lucy is determined to rid Linus of his beloved security blanket over his protests.
