Rock Slab
Rock Slabs are objects that can be seen all around the map of Dredge. They are containers with inventory space that Fish can be placed into, granting some kind of reward for placing the correct fish.
Fish placed in the slab will have their condition frozen.
Shrines
Throughout most of the world, the only Rock Slabs found are Shrines, which have limited space that fish must be fit into in a specific way according to their shape, and grant special items upon completion of the puzzles. You can look up their location on the interactive map.
