Stone Slab

Stone Slabs
Stone Slabs were tablets that hung on dungeon walls. Each Slab was missing a piece, which was located somewhere in the respective dungeon. When the missing piece of stone was put into the slot of the slab, the tablet could then be read by link. All of the provided a clue to a nearby challenge.

The stone Slabs were later replaced by Owl Statues when Link's Awakening DX was released.

Stone Slab Fragments
There was one Stone Slab Fragment found in each of the eight Dungeons on Koholint island. When attached to a Stone Slab, it would give Link a hint, either about a puzzle, a monster, or a dungeon boss or mini-boss.

The Stone Slab Fragment was proceeded by the Stone Beak when Link's Awakening DX was released.
