Best animated movie mistakes of 1966
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?
