When brother and sister help Daddy get ready for his latest gallery show, they meet two other artists: Oana and John-Henry. Sylvia is taken with Oana's work because she uses all natural materials including — porcupine quills! Martin is excited about John-Henry's work because it uses all sorts of welded bits of metal he found at a Junkyard. Once the gallery is ready and everyone has some extra time, John-Henry takes them all to his favorite Junkyard — a very special Junkyard filled with the most surprising (and familiar) treasures!
