Wheeling Gull Isle bridge to somewhere

I have no idea how the island is accessed, I thought it was a sandbar, so I am going with that since the game apparently ate the territory descriptions haha. AW!

The sun was high and the weather warm. The blue-nosed wolf was seated on the beach, the furthest reaching edge of the waves just caressing his toes before they quickly retreated back to the ocean. His tail was thumping on the ground, his gaze focused ahead, not on the endless blue of the salted water, but on the one land mass that found itself floating out there. It was not fully detached, however. Luke had caught a glimpse of a sand bar that was just beginning to peak above the rolling sea, and now the white-furred wolf was eagerly waiting for more of the natural bridge to show so that he could take a trip across and check this island out. If it took too long, he would just swim.
