Bomb rocks are the only enemy of it's type in normal Elona. However, in Elona+ they have more variation. They can be very dangerous, and activate their Suicide attack special action when close. Because they are an exploding type enemy, they will also explode if hit by another exploding monster's suicide attack. This can cause a dangerous chain reaction. Physical attacks that don't kill them can trigger the suicide attack, which is signified by a message that says *click*. This can be triggered with long range physical attacks as well.
