1 to 8 people, everybody on their phone, are a pod of dolphins in a flooded Kansas, and the chalk sea that really covered it 80 million years ago. Roll your dolphin, keep it forever, level it up, laser eyes, a gang with bats, a pod of hundreds, a boat with guns on it. Leap. Flip. Sing together. Work the D.O.L.P.H.I.N. system. Nobody drowns and nobody gets lost.
