The six mischievous leprechauns are on pot of gold duty; moving the pot of gold from place to place. They were planning on landing in the wheat field near Robbie Anderson's house. However, due to a storm they landed right on top of Robbie Anderson's tree house. - rainbow and all!
Normally, they would just readjust their rainbow trajectories, and be out of that tree house before they were discovered.
Unfortunately, Robbie and his dog Sasha were in the tree house when they landed, creating quite a "situation" for all concerned.
Oh, what will those tiny leprechauns do? What will Robbie and Sasha do? Will anyone believe that a rainbow landed on his tree house?
