Spectacle Island is fairly small and has a short wooden bridge connecting its two land masses. Could this tiny bit of land be all that’s left of the fabled Spectacle Rock?
Beedle’s Shop Ship

Piece of Heart #15 and Treasure Chart #17 (via Cannon Minigame)
Climb the ladder and talk to the man sitting near the cannon. For 50 Rupees, play the Cannon minigame by firing cannonballs at five barrels floating at random on the Great Sea. You must hit all five using no more than 10 shots.
Aim carefully before firing and line up the cannon directly with its target. Use your judgment to set the angle of trajectory. With practice, you get used to the power of the cannon and have better luck guessing the degree of trajectory to use.
The first time you win the Cannon minigame, you’re awarded Piece of Heart #15. The second time, you get Treasure Chart #17. For each win after that, you receive an Orange Rupee.
Silver Rupee (via Treasure Chart #22)
Finding and opening Treasure Chart #22 (which is inside the submarine near Northern Fairy Island [C1]) allows you to pull a chest containing a Silver Rupee from the Great Sea near Spectacle Island.
