I am Dolores Huerta

There's a brand-new interactive exhibit at the museum, but one big kid is hogging it and won't let anyone else take a turn. Xavier, Yadina and Brad aren't sure what to do about it, but they do know where they can go to find out... To the Secret Museum! Our heroes are sent back in time to meet someone who was never afraid to speak out against injustice: Dolores Huerta. We find Dolores as a young majorette in a marching band, who speaks up not only to help out her bandmates, who are tired and need a break, but also to help out our trio who have been pulled into the band by mistake! Inspired by Dolores, Xavier, Yadina and Brad head back home and muster all their courage to talk to that big kid, imploring them to let others play, because it's important to always speak up to help people.
