“Yatsuhashi, I think we have a bead on Carmine and Gus. What do you make of this?” Coco said. She pointed to a funnel-shaped cloud of whirling sand moving ahead of the turtle, toward the Vacuo capital city on the horizon.

“Another storm?” Yatsuhashi said.

“Look closer,” Coco said, pointing to the heart of the cloud. Two dark spots were at the bottom of the dust devil.

“Is that them?” Yatsuhashi asked.

“Somehow Carmine can control the sand or create localized weather patterns,” Coco said.

“Bertilak can affect the temperature of the environment around him,” Fox said. “Maybe it’s something similar.”
