Postcard story

Grandma Silver sends Madeleine this post-card, and challenges her to turn the photo into a story. Here she goes:

It.... is.... the.... Eiffel Tower, and the windows are made of glass with snow on the top. And the blue thing coming down is an arrow dragon. The arrow dragon goes side-to-side on the windows and snow. The black things are cannon. The arrow dragon burrows down under the snow to find beatles to eat. If he's unlucky, the beatles will pinch him. The little lines on the 'X' are a cut in the building from the snow dragon. The other lines are for the snow dragon's house. The little black mark is the path the mommy dragon takes to work. The blue dragon knows his mommy because of those lines. The gap means that they are in danger from a grizzly bear. The bottom black line means the snow and the snowflake are friends.
