Whispering Wyrm alerted state

When the wyrm is alerted by a sound or similar stimulus, it enters an alerted state, which blends aspects of its roaming and chasing states. 
In this state, it moves faster than during roaming but lacks the speed acceleration seen in its chasing behavior when slithering in a straight line. Additionally, its head remains upright, as it does not yet possess the ability to rotate and track the player. This is because, at this stage, it is unaware of the player and is simply investigating the source of the disturbance.
