Jacob's brother, Ben, is always king of the castle. Jacob is tired of being the dirty rascal! Jacob and his grandfather decide to set out on a camping trip to Nova Scotia's Kejimkujik National Park. There, they find lots of hidden treasure fit for a king, like emeralds (the green of a hemlock's foliage), amber (the eyes of a deer) and diamonds (in the sky). Jacob even builds himself a crown, and it isn't long before Gramps declares Jacob the King of Keji!
