Trama
A lot of snow fell overnight in the Dragon Valley. Little Grisu gets a lot of sweat when he's cleaning it up. As a reward, Sir Cedric and Lady Rowena invite him on an adventure flight over the South Sea. But the plane has to make an emergency landing. Uncle Joyfire is a savior in need. He's taking everyone to Dragon Island. Again, they are not safe: the island is being invaded.
