BW036: Gotta Catch a Roggenrola!

is the 36th episode of Pokémon: Black & White.
==Synopsis==
While our heroes are having lunch, a Roggenrola comes crashing down on them, ruining their feast! Ash decides he wants to catch it, so he makes a couple of attempts with Tepig and Oshawott. The Pokémon are unsuccessful, and they end up needing to visit a Pokémon Center. All this time, the Roggenrola seems to be urgently trying to tell them something. However, in a hurry, our heroes ignore the Roggenrola and leave it behind.
Our heroes discover that the Pokémon Center’s water source, located in a cave, has been mysteriously cut off. Accompanying a representative from the water company named Garrison, our heroes go to the cave to investigate. We discover that Team Rocket is to blame for blocking the water supply! They’ve also been catching the Roggenrola that live in the cave in order to implement a new weapon Doctor Zager has invented, which concentrates the power of the Roggenrola’s energy core.
Angrily, our Ash and his friends fiercely battle Jessie, James, and Meowth, and soon the Roggenrola are freed. Garrison arranges to have the water supply restored to the Pokémon Center. Ash also discovers the Roggenrola they first encountered wants to go with him. A battle ensues between Roggenrola and Tepig, and this time Tepig prevails. Roggenrola joins the group as Ash’s newest Pokémon friend!
==Episode plot==
A small Pokémon jumps and leaps out of the tunnel. Ash compliments Cilan's lunch, who admits he just used the berries from the forest. A Roggenrola comes and jumps on the table, running the lunch. The Roggenrola appears very upset, trying to warn the heroes of a danger, but Ash thinks it would be good to catch it. Ash sends his Oshawott to fight, who uses Water Gun. Roggenrola uses a dish to redirect the attack back to Oshawott, hitting it back. Ash orders him to use Aqua Jet, but Roggenrola dodges, causing Oshawott to bash into the table, knocking him out. Cilan notices that Roggenrola has a strange thing behind its back. Ash calls Oshawott back and sends Tepig.
Tepig tries to tackle Roggenrola, who avoids the attack. Tepig uses Flame Charge, hitting Roggenrola and knocking the thing away. However, Roggenrola, whose ability, Sturdy, lowers the damage dealt to it. Roggenrola stops Tepig's tacking by using Sandstorm and uses Stone Edge to defeat him. Ash, Iris and Cilan go to the Pokémon Center to heal Tepig while Roggenrola walks away, upset about what happened. At the center, Joy comes to the heroes, reporting Oshawott and Tepig are feeling fine. A repairman comes, telling he couldn't find the problem. Joy explains to the heroes they have no water, so she hired Mr. Garrison to see the problem. He thinks something is in the caves, from where this Center takes the water, in which Roggenrola live. The heroes report they encountered one, making Joy very worried, as Roggenrola never leave the cave. The heroes and Mr. Garrison decide to check the caves.
Meanwhile, Roggenrola tries to warn the other Pokémon, but they hear a strange noise from the nearby mine which scares them away. A machine is taking the Roggenrola, controlled by Team Rocket, who plan on using them to power the machine, intending on conquering Unova. The heroes and Mr. Garrison come to the tunnel entrance, but find no water. The Roggenrola they encountered before leaps and jumps into the tunnel, so they follow it. They soon see rocks blocking the path. Suddenly, they encounter Team Rocket, who take the last Roggenrola. Ash sends Tepig, who uses Ember to free Roggenrola. Team Rocket flees and blocks the passageway. A boulder falls down on Ash, but Roggenrola uses Flash Cannon to destroy it. Team Rocket, however, is pleased they will use Dr. Zager's machine, powered by Roggenrola. They fire it, blocking the exit. Ash saves Roggenrola from the falling boulders. With the exit blocked, Iris brings Excadrill and Cilan his Pansage to dig.
They get out of the cave using the tunnel and follow Roggenrola, who leads them to the abandoned building. Team Rocket is surprised they followed them. Nevertheless, Jessie brings her Woobat, using Gust, so Tepig uses Ember to hit it. The machine releases the power, though Roggenrola uses Flash Cannon to intercept the attack. Team Rocket fire the cannon, but Roggenrola counterattacks. Nevertheless, Team Rocket use their cannon, but see Roggenrola reversed their power, so they are freed. James brings his Yamask and it uses Night Shade and Woobat Gust. Tepig used Ember, Roggenrola Flash Cannon and Ash's Pikachu Electro Ball, but Team Rocket depart away on their jet packs. After the battle, Nurse Joy heals the Pokémon.
Mr. Garrison reports he will call a team to repair the plumbing system to get water flowing once more. The Roggenrola Ash saved goes outside, wanting a battle. Ash sends his Tepig, thinking he would want to give another shot of battling Roggenrola. Tepig starts by tackling, but gets pushed by Sandstorm, followed with Stone Edge. Roggenrola uses Flash Cannon, so Tepig uses Flame Charge, colliding with each other. Tepig clashes with Roggenrola, though both sides do not give up. Tepig tackles Roggenrola a final time, knocking it out. Ash throws the Poké Ball at Roggenrola, catching it.
