What does the paw immediately do after the first wish in the monkeys paw?

After the first wish is made in "The Monkey's Paw," the paw moves in a strange and unsettling manner, as if it is responding to the wish. Mr. White wishes for two hundred pounds, and shortly after, the family receives the money through a tragic event involving their son, Herbert. The paw's movement foreshadows the dark consequences of tampering with fate. This reaction sets the stage for the unfolding Horror of the story.
