As Ash and co. travel to Lilypad Town and Dawn's next contest with their new friends Khoury and Lyra, they decided to stop in a Pokémon center, Brock flirts to Nurse Joy again but only to be attacked by Croagunk. When suddenly, three kids along with their fainted Pokémon consult Nurse Joy, the three kids tried to catch a wild Gible, but fails. Nurse Joy warns Ash and co. then consults the three kids' fainted Pokémon while Brock offers his help. Ash finally decides to catch the rude Pokémon, Khoury was afraid because he thinks that it is too dangerous to catch the wild Pokémon, then the company make their way to catch the Pokémon.
Along their way, Lyra asks Dawn of what she thinks of having Khoury as her boyfriend, the question surprises Dawn, Lyra told her that they will be a great couple in the future which makes Dawn panick. Suddenly, along their way, a big rock came flying towards them which was intentionally caused by the wild Gible. After Khoury checks Gible's data on the Pokédex, the wild Gible uses strength and throw another big rock at Ash and co., they quickly dodges the rock then Gible uses rock smash at the rock. This amazed Ash and Khoury, the two decides to catch and raise the strong Gible. Ash sends out Buizel while Khoury sends out Totodile, the wild Gible uses Sandstorm at them then quickly dug a hole. It totally amazed Ash and Khoury, Lyra suggested to help Ash for Dawn to keep an eye on Khoury, then they follow the wild Gible. Team Rocket was eavesdropping the whole time, they want to give Gible to the boss because of its amazing power. Ash and Lyra with Buizel continues to look for Gible, Lyra spotted the Gible, and its moving very fast, Ash commands Buizel to use Aqua Jet at the fast moving Gible, when Buizel was about to hit Gible's dorsal fin, the Gible completely hides the fin and dodges Buizel's attack. The Gible changes course with Lyra spotting it the second time, Ash commands Buizel to aim Water Gun at the fast Pokémon but fails when it dodge the attack using the same strategy. Then Gible jumps, Buizel uses SonicBoom but easily dodges by the Gible. Gible moves at a top speed towards them, Ash commands Buizel to intercept it with Aqua Jet but dodges by the fast-moving Pokémon, Gible chased Ash and Lyra as they run through the grasslands, Lyra was afraid that it was able to catch up, Pikachu uses Thunderbolt at Gible but again dodges the attack with the same strategy, the Gible jumps and uses air to keep Ash, Lyra and Pikachu away, then it suddenly disappeared from their sight. Ash realizes that catching Gible was harder than he thought it would be. Dawn saw that Ash and Lyra was having a hard time catching the Pokémon, while Khoury decides to wait for Gible than to chase it by using a rod, he also gives Dawn one. When Khoury's rod suddenly shakes, they taught that they caught Gible but instead of Gible, Piplup was the one that is caught on his rod. Ash and Lyra came up with a different plan of catching Gible, the Gible suddenly appeared pissed and rushes toward Lyra, Lyra jumps at the rock so that Gible cannot follow her, but much to her surprise, the Gible breaks the rock where she stands. Lyra told Ash that she was fine and instead look for Gible. Ash spotted Gible coming at Dawn and Khoury, he warns them that Gible was on their way, he commands Buizel to use Aqua Jet while Khoury commands his Totodile to use Aqua Tail and both aim at Gible. But Gible keep out of the way and instead make the two Pokémon attack each other, this makes the two Pokémon fight. Ash and Lyra tries Khoury's way of catching Gible by using rods, Khoury come up with an idea of putting a Pokémon food only for Ground and Dragon types at their own rods to attract Gible. Meanwhile, Dawn's rod attracts the wild Gible and start shaking her rod, realizing that it is very strong, Dawn cannot reel the rod anymore but she was helped by Khoury, Lyra was thrilled of the two. When they are about to reel the rod in, Gible pulls the string which also pulls Dawn and Khoury. Gible breaks the rock they were standing at then it run at full speed away from them with Ash chasing it. Khoury uses a sensor at the ground to feel Gible's presence, Lyra sends out her Marill and detects Gible's location. Team Rocket saw Ash and co. and follows them, Khoury senses that Gible was on a nearby cave but he also warns Dawn that its dangerous and need to be careful. Ash, excited to catch Gible, runs into the cave with no worries but then fall through a Trapinch sandtrap. After he was saved by Khoury, the two argued because of Ash acting so recklessly. They soon entered the cave trying to search for Gible, the four splitted into two groups, Ash with Lyra then Dawn with Khoury. Marill assisted them in finding the Pokémon, Marill detects that the Gible was in underground so Ash sends out Monferno and tells it to use Dig everywhere. Unfortunately, Monferno pisses a bunch of Diglet and Dugtrio, the Diglets and Dugtrios carry Ash and Lyra along with their Pokémon into some part of the cave with Dawn and Khoury chasing them but fails to follow them and loses their tracks. Khoury and Dawn, finds the cave to be a maze and was chased by an angry Onix, inorder to escape the Onix, the two split up and Onix hits the wall, awaking bunch of Zubat. Ash and Lyra escapes the Diglets and Dugtrios, they soon hear voices of Dawn and Khoury but before they could run into them, they were attack by bunch of Zubats. Dawn and her Piplup finds Khoury, but meets Ash instead.
Lyra, being alone with her Marill, was later contacted by Khoury through her PokéGear and instructs Lyra to tap in the cave's wall so that he can find her through his sensors. Soon the four meets up and decides to find the exit first before finding Gible. Ash and co. finally come out of the cave, outside, they found the rude Gible and seems to be ready for battle and all fired up. Ash and Khoury are ready to capture the wild Gible, but Dawn and Lyra convince Ash to let Khoury have a shot. Khoury sends out Totodile,
Totodile uses Aqua Tail but Gible stops it with its Sandstorm, Gible quickly uses Strength and aim a rock towards Totodile, Khoury tells Totodile to catch the rock and use crunch and Totodile completely shattered the rock, Khoury commands Totodile to use Superpower but Gible catches the boulder and breaks it by using Focus Punch. The team cheers for Khoury, while Gible gets a nearby boulder and shattered it through its head, showing how tough it was, Totodile did the same too, the two Pokémon continues to shatter big and bigger boulders through their heads to show that they are much stronger than the other. The two Pokémon shatter two big boulders using their heads, but it seems that Gible doesn't want to lose so it gets very large rock that shocks everyone that it might crush Gible, Gible splits the large rock into two parts which exhaust Gible and completely weakened but Gible tries to escape using Dig but before it could escape, Khoury commands Totodile to use Water Gun at the hole, the attack hits Gible and drive it out of the ground, Khoury told Totodile to use Aqua Tail which hits Gible, Khoury saw his chance, he throws a Pokéball at it and Gible was caught. Ash and co. congratulates Khoury of his success. Team Rocket is still in the water, hoping to catch the rude Pokémon, thought that they caught Gible into Wobbuffet's rod, but instead they caught a Sharpedo which continues to chase them. Back at the outside of the Pokémon Center, they have their dinner along with their friends,Brock told them that Lilypad town was their next stop for Dawn to earn her next ribbon.
