Nina and her brother, Dave, are playing music with the Best Friend Band today. But they can't start because Dave lost his favorite musical instrument from Cuba! Elmo, Abby, and Tamir help look, and they come across something new, a wooden cricket. They try to figure out what it's for when Dave spots the wooden cricket and tells them they found his instrument. This wooden cricket guiro is special to Dave because his uncle gave it to him when he was a little kid in Cuba and taught him how to play. Elmo, Abby, and Tamir learn that the wooden cricket is a guiro, a percussion instrument that you play by scraping a stick on the ridges. They are fascinated to have found something new and learn all about it. Now that Dave's instrument has been found, the Best Friend Band is ready to play music!
