It's springtime on the farm, and that means it's time for Mike and Molly's birthday. As the flowers bloom and the birds are singing, the cheerful little sheep set off to gather everything they need for a real birthday party: decorations, presents, and of course a delicious cake. Along the way, they sing happy songs, tell jokes, and discover all sorts of things about colors, shapes, and numbers together with the children. But there's one small problem... The bridge over the ditch is broken, and Mike and Molly can't get across. Mike comes up with the craziest ideas to reach the other side-using balloons, roller skates, and even a rocket. Will they manage to collect everything in time for the birthday party?
