Krokorok was used in Clay's battle against Ash Ketchum's Oshawott. Oshawott started with Aqua Jet, but missed, since Krokorok dug in the ground. Krokorok emerged out and started a Sandstorm, which caused Oshawott's sight to be lowered. Krokorok bit Oshawott, who failed to hit Krokorok with Razor Shell (due to the sand getting to Oshawott's eyes) and was hit by Krokorok's Stone Edge. Oshawott used Water Gun above the field, canceling Sandstorm. Krokorok attempted to dig, but Clay's strategy was countered by Oshawott, who used Water Gun in the hole. With Razor Shell and Aqua Jet, Krokorok was defeated by Oshawott.
