A Rainy Dragon Day  – Picture Book - by Julie Völk (Author, Illustrator)
 
What's more perfect than a day on the sofa while the rain patters on the windows?
 
I'm just settling down with books, cocoa, and my long-haired dachshund, when the doorbell rings. It's Fred the dragon, hoping to use the bathroom. There's nowhere suitable for a fastidious dragon. After rejecting all the usual places, Fred sweeps us off through the storm to a magical world of floating pagoda bathrooms.
 
Every beguiling detail in these illustrations evokes the snuggle of a cozy, rainy day in a funny story that addresses the very necessary question of where dragons go when they need to go.
