Meet Mac, a curious, dramatic, and slightly clumsy Macaroni penguin with a heart as big as the sea. When Mac joins the crew of the cruise ship SS Adventure, every day brings a new adventure…and a little bit of trouble. When the ship docks in Rio de Janeiro, Mac discovers a city bursting with music, dancing, and dazzling costumes. Determined to add Samba to his act, Mac jumps beak-first into practice. But in Rio, dancing isn't just about moving fast—it's about listening, learning, and knowing when to step in. With the Copa Ball sparkling, the Sambadrome booming, and feathers flying everywhere, Mac must figure out how to join the rhythm without causing a wobble. Full of laugh-out-loud humor, vibrant Brazilian flair, and heartwarming growth, Mac in Rio de Janeiro is a joyful early chapter book perfect for fans of Narwhal and Jelly, Magic Tree House, and The Bad Guys. Will Mac find the rhythm of Rio…or step on his own feet?
