This is what we found on Wikipedia regarding the Bluey's Big Play:

The Missoula Children's Theatre (MCT) is a touring children's theater program that travels across the United States and internationally, casting local youths in performances of original plays based on classic children's stories. Based in Missoula, Montana, it is part of MCT, Inc., a nonprofit, 501(c)(3) organization that employs about 120 full-time staff members and also includes the Missoula Community Theatre. The Missoula Children's Theatre is believed to be the world's largest touring children's theatre.

The mission statement of MCT is "the development of life skills in children through participation in the performing arts". The organization has traveled to 50 states, 5 Canadian Provinces and 17 countries. One goal of MCT is to "reach the small communities that have few creative outlets or resources for their children", and to "[help] our country's children grow into confident, successful citizens using the positive results of our programs". Traveling to over 1,000 communities annually, MCT works with roughly 65,000 children a year who perform in plays, and their theater workshops reach 150,000 young people in underserved areas.
