On Monster Day (a day for monsters to celebrate being monsters), the monsters of Sesame Street sing about how they'll be celebrating the festivities. Maria and Luis, however, sing that they'll be sequestering themselves inside for the duration of the holiday. Despite the chaotic monster antics, Big Bird believes he'll enjoy participating in the Monster Day fun.
