Tremor Under The Rock

“Yes, you are right. I can hear the sound, a sound of tremor under the rock,”
The elephant was worried about the tremor he felt under the rock. The hippo said he also heard the sound. As they were talking, there was a big thunder in the sky, lighting the entire place they were standing. It was the beginning of a thunderstorm.

It rained for several days flooding the rivers in the forest.
