As the other sudden disappeared from his line of vision, Bruce turned about, an unadulterated expression of worry spreading across his face. “Mate! Ye’lright?” the great white shouted until his gaze finally settled on the other, having dropped from his current location. At the sudden rickety movement of the panels, the shark squinted under the light, making out a narrow hole. “Well, looks like you can fit through.” 

“I can,” the Repairman replied, turning back around, "but what about you?“

Bruce, despite his Tooniness, was still a rather large shark, and CG characters tended to have a harder time squeezing through smaller spaces.

"There,” he said. “I’ll let you know what I find.”
