i got a idea of a underwater map, its like the water tunner u go though but half map long, then u go on a long island and a ramp goes high and u glid to another tunnel sticking out of water and u get to finish line in water. there is a twist tho, there are two tunnels and one leads to a shortcut to the finish, the other leads the long way around( the straight way)the finish line is on a little island where u also start. the two tunnels collide halfway to finish but there is still a fence that devids the tunnels.
