Tina is going through the heartbreak of puberty; once they see it is not contagious, Gene and Louise try to cheer up their big sister. They show her what they believe is a smelly special needs breakdancing class in Brazilian. Tina's hormones are fueled by lithe, muscular Jairo and his martial art, Capoeira. Soon, it is "Jairo says this" and "Jairo says that" and Tina is neglecting her job, working night and day, to master Capoeira. Tina wants to earn her yellow corda in the Troca de Cordões ceremony, Portuguese for "exchange of strands."
