When Caillou's family makes a springtime visit to Jonas' ranch, he takes them on a sleigh ride to a maple forest where Caillou discovers how the maple sap is collected from maple trees. At the sugar shack, Caillou learns about the maple syrup transformation process. But the best surprise is outside, when Jonas pours the hot syrup on the snow and everyone gets to enjoy Caillou's new favorite treat, maple toffee!
