Calista was wandering on a mountain and her Baltoy got lost. Since it was a Ground-type, Pikachu's Thunderbolt did not work, so he used Quick Attack, which knocked Baltoy away. Calista was angry, but Ash pointed out Baltoy would've fallen down a cliff. As they were walking, they heard a distress and found Team Rocket battling a cloaked woman. Cacnea used Pin Missile on the woman's Xatu, but Xatu blocked the attack with Reflect, uses Teleport and Pecks Cacnea. After Team Rocket noticed Ash and Calista, Cacnea attacks them with Pin Missile, but Baltoy reflected the attack with Rapid Spin. After Pikachu stops Seviper with Thinderbolt, Xatu blast Team Rocket away with Shadow Ball. Inside the ancient ruins, the woman asked Calista to lift the rocks, as her own Baltoy got trapped inside. Thus, Baltoy used Confusion, which lifted the rocks and allowed the woman to call her Baltoy in its Poké Ball. The woman asked of Baltoy to use Rapid Spin on the wheel, where her own Baltoy was trapped. However, Team Rocket arrived and caused trouble with their machine and grabs Calista's Baltoy. After Xatu's Peck didn't work on the machine and Pikachu uses Thunderbolt on the machine's arm to free Baltoy, Calista had Baltoy use Rapid Spin, which destroyed parts of the machine and allowed Xatu to, once again, blast Team Rocket away with Shadow Ball. As the woman requested once more, Baltoy spinned on the wheel, which activated the mechanism, revealed to be a time machine. In the end of the day, Calista promised to become an archaeologist and ran off with Baltoy away.
