Continuity mistake: When Snoopy arrives at the Halloween party, he slides down a set of curtains and then hides behind those curtains. In the same shot, Lucy approaches a tub of water atop which five apples are floating. When the shot changes, there are only four apples floating in the tub and Snoopy has now somehow gotten into the tub and is hiding under the water. The action is constant. How did Snoopy get from behind the curtain to under the water? (00:18:30)Professor Zed
Other mistake: When the kids leave Linus standing alone in the pumpkin patch, Sally decides to rush back to Linus, and when Linus explains that she'll see the Great Pumpkin with her own eyes, Sally's left arm is blue, the same color as her dress, then instantly changes to the normal flesh color within the same shot.

Continuity mistake: The fence which Linus tries to shove the pumpkin through at the start of the show, loses planks from one side to the next. On one side, the fence (to Linus's right) has nine planks. When the view changes to the opposite side, this same section of fence now has only seven planks. (00:01:05)Professor Zed
Continuity mistake: When Lucy and Linus return to their home with the huge pumpkin, the house's surroundings are changed from what was seen just moments earlier at the beginning of the show. A bush next to the steps has gotten smaller and there is now a walkway leading to the house. (At the beginning, there seems to be nothing more than grass outside the front of the house.) Also, a tree, a garage, a telephone pole, a second house and a garbage can which they walked past at the start of the show, are not there when Lucy and Linus return home. (Though their own house steps have changed when Lucy and Linus return, it may simply be that they are now in shadow as the sun has, by then, gone down in the sky significantly.). (00:01:30)Professor Zed
Continuity mistake: After choosing their pumpkin in the patch, Lucy is seen walking through a fence via a missing plank. The view then switches to the other side of the fence. Linus attempts to shove the huge pumpkin through the fence, but it won't fit. We then hear Linus rolling the pumpkin to the far end of the fence after which Linus and the pumpkin come back into view. However, after initially trying to get the pumpkin through the fence, although we have a great view through the fence, we never see Linus or the pumpkin go past the missing plank.

Continuity mistake: When Snoopy approaches the pumpkin patch, crawling on all fours, the moon is white, medium-sized and partially up in the sky. When the shot changes to Linus and Sally, the moon is yellow, gigantic and touching the horizon. After Sally's disillusionment, the moon disappears from the sky. (00:21:15)Professor Zed
Continuity mistake: When Linus is rolling the pumpkin, the position of the pumpkin goes from upside down to right way up between shots.
Continuity mistake: When Linus is rolling the pumpkin on the path, the path is plain, but when we see Linus following Lucy in the next shot, the path is slated.
