Sand Buffalos

Ban felt the sand beneath him shake. It's as if an earthquake is currently occurring. He glanced at his back and noticed that Delo and Belle were still not aware of it. 

The second to feel the tremor was Eva who was currently in her combat form, followed by Delo's Barrier Turtle. Eva immediately jumped towards Ban's shoulder and the Barrier Turtle knocked its round head on the feet of Delo. 

"Hurry, follow me!" Ban shouted desperately as the tremor beneath his feet kept on getting stronger. He ran away as fast as he could, his destination was the highest peak of the Sand Valley they saw earlier.

At this point, Belle and Delo had just felt the earthquake. 

Upon hearing 'Leon', Belle did not hesitate for a second as she also ran as fast as she could to follow behind him. She already felt the earthquake and even though the voice produced by Leon was still strange to the ears, she somehow felt the urgency brought by it.
