Lucy will use it to trick Charlie Brown. You play the football scene after Snoopy corrals the leaves and Linus jumps into them. Following him back to the mailbox, you find that he left his blanket in the leaves. Recover it for him and he mails his letter to the Great Pumpkin. Now you can go left to Charlie Brown's yard for the football scene.
Earlier, when you rolled to pumpkin home for Linus, you got a trick-or-treat bag. Giving this to Pigpen gave you a lemon lollipop, which you gave to Linus to get his invitation to the Halloween Party. At that time, you should have recovered the pen he was using, as you need it for the football scene. If you don't have it, go back to the house -- it is sitting on the desk.
After the football scene, Lucy leaves the football. Pick it up and use it at Snoopy's doghouse to begin the imaginary Red Baron / World War I scene.
