On the way to Solaceon Town, our heroes reach a river with an unfinished bridge. Brock immediately falls for Isis, the stonecutter working on the bridge, and learns that construction has halted because Isis's Bibarel refuses to cut any more stone. With only days until the project deadline, Isis's job is in trouble, and Brock gallantly offers to help get Bibarel back to work. But to his surprise, even the lure of delicious Pokémon food can't convince Bibarel to resume cutting.
Isis doesn't know what's wrong—Bibarel was trained by a master stonecutter and always used to obey her commands. But once the stonecutter left, Bibarel stopped working. Brock and his friends try to make up for the slack by having their own Pokémon cut stone instead, but without Bibarel, they don't have the know-how to cut stone to the right specifications. To make things worse, Team Rocket descends on the scene and steals the construction team's Machamp and Machoke!
Bibarel beats Team Rocket and frees the kidnapped Pokémon, but the bridge's head engineer shows up at the quarry and tries to force Bibarel out of the way so work can resume. With help from our heroes, Bibarel defeats the head engineer and his Pokémon. Then Bibarel's original master returns, and reveals that the head engineer's blueprints were flawed. That's why Bibarel refused to cut any stone! Using the corrected blueprint, Bibarel gets back to work and the bridge is finished on schedule.
