Based on the book “Pablo and the Coffin” (Pablo y El Baúl)by Jaime Mijares, it adds the main character of Nicholas, a 10-year-old boy with Down Syndrome.
The lovable to look at Nicholas has lost his mother, and leaves with his loving (but somehow oddball) grandparents. To celebrate his birthday, each year his mother made a different costume: a monkey, a pirate, a giant dragon. Nicholas thought he would never need them anymore, but he does. His cousin Nicolas, angular-shaped and a nerd for planes (also with an absent father) suffers from nightmares. The only way to cure him is for Nicholas to open up this old trunk with magical costumes and transpose him to a magical adventure.
