One morning at the family nest, Don befriends a butterfly that he names Dan. Don, Buddy, Tiny and Shiny watch Dan and three of his "sibling" butterflies fly around until suddenly they disappear, leaving Dan all alone. Don feels for the separated butterfly and vows to re-unite him with his siblings.
