PLOT
When Thomas discovers batucada music, he's thrilled to be invited to start the carnival and uses the sounds of his noisy trucks to create his own fun beat! Meanwhile, Raul's super-competitive nature gets him into trouble and Thomas learns not to judge an engine by their colour when Gustavo (who reminds him of Gordon) offers advice. Back on Sodor, Percy's panic causes confusion and delay, Diesel uses tricks to try to prove his usefulness and Emily gets the adventure she has longed for when she and Nia camp out all night with the Sodor Rangers!
