Charlie Brown decides that Snoopy needs to educate himself, and gives him his library card to check out a few books. Snoopy decides to take out one book, a book about magic, which after reading, influences him to hold a Vaudeville show. During the opening, Snoopy practices magic with Woodstock by his side. Charlie Brown warns both of them that the cat next door will get upset if he and Woodstock get loud. However, Snoopy and Woodstock continue to perform more magic tricks and the cat next door angrily rips Snoopy's doghouse apart. Snoopy recruits Marcie as one assistant and announcer, and Sally as his silent assistant. In the show, he pulls Woodstock with rabbit ears out of his hat and does a ring trick that goes wrong. Both of these tricks raise the ire of a bully, but Snoopy shuts him up. He also does the "stick-in-the-hole" trick to Franklin, the "amputation-decapitation" trick to Peppermint Patty, cutting Linus's trademark security blanket into strips, the levitation trick to Lucy van Pelt, and biggest of all, making Charlie Brown literally disappear. '' CBS advertisement, April 1981 A sudden rainstorm ends the show early, and Charlie Brown is left invisible. Convinced he is going to remain that way for the rest of his life, he prepares to roam the world as a lost soul, and Sally begins moving her stuff into his room. Before Charlie starts roaming, he decides to feed Snoopy to show him what has happened. When Snoopy realizes he cannot yet reverse the trick, he tries a couple of different ideas to make Charlie Brown visible: first by dousing him in soap and water, which fades immediately, then coating him in mud and using a hairdryer to solidify it but this crust soon breaks off as well. Finally Snoopy drapes a sheet over his head and gives him a necktie to fasten it, along with some oversized shoes. Charlie Brown goes inside, which scares Sally and when he looks in the mirror and sees that Snoopy made him a ghost, he faints. A little while later, Linus tells Lucy that Sally told him that even if you look at Charlie Brown, you don't see him. Lucy frowns and says, "What's that's supposed to mean? That's the dumbest thing I've ever heard." Despite this shortcoming, Charlie Brown realizes he has a golden opportunity to kick Lucy's infamous football without her usual prank of pulling it away at the last second. Taking advantage of his invisibility, Charlie Brown finally kicks the ball out of a bewildered Lucy's hand and then taunts her about it. Furious over Charlie Brown succeeding in kicking the ball, Lucy gets the magic book and hands it to Snoopy. She accuses Snoopy for making Charlie Brown disappear and says he better make him reappear. Then she threatens him that if he doesn't make Charlie Brown visible again, she is going to pound him. After starting out by entering his doghouse lab and working with chemicals so volatile, they explode and start a chain reaction of explosions that chase him out of the house, Snoopy continues to study the book, and tests a number of counterspells on Woodstock, he goes about casting his counterspell in all directions, unsure just where Charlie Brown is. As Snoopy wanders into a vicinity where Lucy is setting up another place-kick, Charlie Brown happens to run by where Snoopy is practicing. Just as he is about to kick the ball again, Snoopy casts the counterspell in Charlie Brown's direction, causing him to unknowingly become visible again. Lucy witnesses his reappearance and pulls the ball away for the eleventh time as Charlie Brown winds up to kick it, then promptly falls flat on his back. However, Charlie Brown fails to display embarrassment and says that he finally kicked the ball, though Lucy considers this a false statement, saying no one will believe him. When Charlie Brown tells Lucy that Snoopy will believe him, she scoffs at Snoopy's magic abilities. The insulted beagle magically levitates Lucy into the sky like he levitated her during the magic show earlier, and leaves her stuck there as payback. Snoopy and Charlie Brown dance away to conclude a satisfying day, ignoring Lucy's pleads to get her down. Linus eventually pulls Lucy down with his blanket during the closing credits. However, Lucy becomes angry and embarrassed about what happened. She gives up and stomps away.
