In Brookhaven, siblings Niko and Lena launch the Future Fund Builders club to turn daydreams into a magical playspace beneath the old stone bridge. Through bake sales, handcrafted riverstone tokens, and joyful community events, they learn to save, budget, and adapt when challenges arise. Neighbors deposit coins into a clear jar while logging every expense in a shared ledger app. When lumber prices spike, the club's budget committee finds creative solutions, and a surprise donation keeps hope alive. As they surpass their coin goal, Brookhaven unites for a picnic and a groundbreaking ceremony—celebrating teamwork, financial savvy, and the power of community.
