It's one of those days where there's nothing to do, and the kids are looking for an activity. Inspired by Papi's story about how he used to look for coqu's in Puerto Rico, Alma and friends search the park for the tiny frogs. But how fun can a game be when you're looking for something that;s pretend? Andre has drawn a chalk art mural on the sidewalk from his building all the way to Alma;s house. He calls it "Chalk the Block," and everyone is invited to come see it. But a heavy rainstorm washes his hard work away! Can Alma find a way to help Andre re-do his art before everyone arrives?
