Linus Van Pelt is criticized by the other kids, except
Charlie Brown, for always having his blanket with him, but Linus ignores them, loving it no matter what and insisting on never outgrowing it.
Snoopy agrees with this and tries to take it for himself, but fails. One day,
Lucy Van Pelt informs Linus that their grandmother is coming in a week, and if Linus doesn't get rid of his blanket, it will be cut up into pieces by their grandmother. Charlie Brown suggests that Linus find a substitute for the blanket, which though only works to some extent. Lucy tries various attempts to make Linus let go of his blanket, such as locking it in the closet for the day, turning it into a kite and letting go of the string, causing it to fly away and get lost before it is eventually found, and burying it outside, but all the attempts fail, and Linus is still obsessed with it. Throughout the special, the other characters also have various problems of their own: "
Pig-Pen" is also criticized by
Patty and
Violet for being dirty, and Lucy constantly fails to get
Schroeder's attention. Days later, Snoopy drags Linus and his blanket across the neighborhood, which all the children follow as they get affected in their path. After all the other children, except Charlie Brown, criticize Linus to his limit, he finally snaps and delivers a monologue about how everyone needs some kind of security, while pointing out their own securities that are like his blanket (
Sally Brown's being "Sweet Baboo"s, Schroeder's being Beethoven, Lucy's being Schroeder, and Snoopy's being suppertime, "24 hours a day"). Later, Grandma Van Pelt arrives, and Linus gives her a washcloth as a decoy of his blanket. The story ends with Linus trying to get his blanket back after Snoopy steals it, shouting "AUGH!" == Voices ==
