When Coyote lays out the picnic, he initially lays out a sugar bowl, a thermos of coffee, his plate and silverware, and a jar of something (presumably jelly). When Bugs emerges from his hole, the jar is there, but, as soon as the view changes and Bugs is walking around the picnic setting, the jar is gone.
When Coyote lays out his picnic, his silverware includes a fork, a knife, and spoon. When the view changes to show Bugs walking behind and around the picnic, the spoon has disappeared. Note that the sugar bowl, which Bugs uses as a coffee cup, already had a spoon in it when Coyote laid it out.
