Jagged Rocks

 are rocks that can be found in the Shark Stage. They are quite abundant in the area. It is larger than an ordinary Rock and one hits any Block, except for any merged block. Due to its shape, players who have fell out of their boat may instantly die when they contact the rocks.

The Jagged Rocks come in multiple various shapes, but most are too steep for the player to jump on in an attempt to get back onto their boat. Speed boats are most vulnerable to this obstacle, as they fly close by the tall obstacles, and may get hit when moving around the 'Shark Island' of the stage that the rocks spawn in.
