After Linus jumps in the leaf pile, he leaves without his blanket.
When he asks about it, go back to the leaf pile in Charlie Brown's backyard and click on it. You can blow away the leaves and reveal Linus's blanket. This works better by not clicking when you move the mouse. Bring it back to him at the mailbox.
(You have to follow Linus and click on him, thengo back. You cannot click the leaf pile before he goes to the mailbox and asks about the blanket.)
