It was a soft chirping, akin to that of a small bird...
If it weren't for the clear weather or the silence of the late night, he would have easily missed this tiny sound. But now that he had heard it, he couldn't help but investigate its source.
He followed the sound for a while, only to find it had stopped.
But he was not in a hurry, time wasn't pressing, so he leisurely roamed around the forest. Eventually, he transformed into a Deinonychus and strolled around the woods at a more leisurely pace.
It wasn't because he was fearful of any potential danger; it was just that he thought the Deinonychus would have better hearing abilities.
When he heard the sound again, he felt dejected, realizing that he had seemingly walked in the wrong direction and drifted farther away.
The Deinonychus has light and agile footsteps. He quickly turned around and trotted in the direction of the sound.
