Smith, J. D

Everyone in Gustavo's family is in a mariachi band except Gustavo, who doesn't know how to play any of the instruments.

Kate and Mim-Mim must race against the clock to repair Tack's letter launcher in time to mail their Christmas letters to Santa Claus.

Gustavo's dreams of joining his family's mariachi band are limited by his inability to play an instrument, but he finds his talent after being inspired by the beauty of the desert. Presented in English and Spanish.
