An ordinary rock leads to a spectacular adventure! When a group of kids find an ordinary rock on the playground, anything can happen. "It's a dinosaur seed!" Flora declares. Wyatt and Cece immediately catch on, and the three kids plant the seed and wonder what it will grow into, building on each other's ideas. But Victor is confused. "Rocks don't grow," he says. "Even if you water them." Before he misses out on their adventure, the friends help Victor find his own way into the game. Inspired by the improv concept "yes, and . . . ," The Dinosaur Seed captures the creativity and authentic voice of kids left to their own devices. The individual personalities of Cece, Flora, Wyatt, and Victor shine as they dream a boring rock into a spectacular adventure together, modeling cooperative, inclusive play.
