Street artists Sainer and Bezt of  The Etam Cru painted this charming picture of a young boy brushing his teeth and playing in the water with a boat and Godzilla by the spigot for the Urban Samtidskunst in Oslo, Norway.

The pictures below give you an idea of scale for this monumental task.  To reach the boy's mouth, a cherry picker crane was used.
