Prompt #3: Under the covers
The main character is a boy who is on a winter vacation and he is snowed in with his family. One night he is very cold and asks his father for extra blankets. His father brings a very old blanket that has been in the family for a very long time. This blanket has magic powers that can take you into a fairy tale story. The boy finds himself in another world on a magical adventure. When he finishes the journey he comes out and his father asks him if the blanket kept him warm as an inside joke to let his son know he knows what happens when you go under the covers.
