What happens when the super chat goal is reached in this YouTube stream?

When the super chat goal is reached, the content creator will deliver two exciting rewards for viewers. First, they'll create an AI-generated song specifically about construction, which appears to be the creative component of the challenge. Second, the host will perform 75 jumping jacks as a physical challenge element, adding an interactive dimension to the stream. The goal specifically required ten teal-colored super chats, which according to the transcript has just been officially reached, triggering these promised activities.
