Deadrock

Deadrocks are rock-based creatures that make their home on the side of Death Mountain in and, and in the Death Mountain Foothills of.

A Link to the Past
In, Deadrocks are bipedal creatures with tiny wings, although they have never been seen flying. When they are hit with weapons such as a Sword, they will morph into impenetrable rock statues and remain in that state for a few moments before transforming back to their normal, mobile form. The statue form is invincible, though they will not cause damage, so Link must pass while they are stunned. Though they are normally invincible, if Magic Powder is sprinkled on a Deadrock or if Link uses the Quake Medallion, they will become Slimes, rendering them mortal.

Four Swords Adventures
Deadrocks in Four Swords Adventures are similar to their A Link to the Past counterparts, though they may be destroyed by fire and can be crushed with the Magic Hammer.

A Link Between Worlds
Deadrocks in A Link Between Worlds have the same behavior as those in A Link to the Past. However, when turned into stone, they are venerable to the Hammer and Bombs.

Trivia

 * Their small angelic wings and their defensive abilities may be where the name, "Deadrock," comes from.
