Peril

 See It on A Postcard's Thursday Postcard Hunt - Legends and Children's Stories

I imagine there are lots of legends abut the sea in Brittany. This one features L'Ankou de la Mer. The card shows the stretch of sea between Pointe du Raz and Isle de Sein which has always been a place of danger for sailors. If a boat in these parts encountered 'Bag Noz' (boat of the night) it was sign of imminent death. The first drowned person of the year became Ankou of the Sea, and took the place of the captain of the sinister boat. The Bag Noz could appear at any moment but disappeared as soon as anyone tried to approach it. It was especially important not to try to follow it because it led directly to the reefs, which are numerous.

This is a Winnie the Pooh story of when Seven Acres Wood flooded. Pooh bear took his honey up to a branch of a tree and stayed there until on the fourth day there was nothing left. The chapter is called  'In Which Piglet is Entirely  Surrounded by Water'. Pooh spots Piglets message in a bottle asking for help, it looks like a honey jar so that gets Pooh bear down from the tree.
