Gone With the Windworks! (Japanese: ダンジョン攻略！？ 谷間の発電所！ Dungeon Capture!? The Valley Powerplant!) is the 144th episode of the Diamond & Pearl series, and the 610th episode of the Pokémon anime. It first aired in Japan in a 1 hour special on September 17, 2009, along with An Egg Scramble! and in the United States on February 13, 2010.
Khoury and Lyra join the group and travel together. The episode starts off with the group relaxing for a lunch break. As Lyra and Dawn comment on her newly hatched Cyndaquil, Piplup offers his greetings. Piplup's first try is returned with Cyndaquil turning its back away. Devastated, Piplup tries once more only to meet the same greeting. Angry, Piplup then pecks Cyndaquil's behind which it also pays back in kind. The two are then ready to brawl when Pikachu breaks them up. Ash then suggests to have a battle to find out more about Cyndaquil's personality and strength, to which Cyndaquil agrees. With Brock as referee, the battle starts off with Ash choosing Grotle and Dawn checks Cyndaquil's moves with the Pokédex to find that it knows Flame Wheel, Swift, and SmokeScreen. Grotle starts off with Razor Leaf, which Cyndaquil dodges by jumping up high, and then uses Flame Wheel. Grotle takes the hit and Ash commends Cyndaquil on the power of its move, which causes it to jump with joy. Grotle then uses Energy Ball which Cyndaquil dodges again and then uses Swift from above. It is powerful enough to cause Grotle to be pushed back which Khoury and Lyra comment on it's excellent first time and agility. From a hill, Team Rocket observes the battle where Jessie and Meowth plan to swipe the Pokémon only to be reminded by James that they have something to attend to. Lyra's Marill hears them and wanders off... Cyndaquil dodges another Razor Leaf and uses SmokeScreen from above. From the ground, it uses Swift to cause Grotle to flip over! Ash responds with a Rock Climb that lifts Cyndaquil in the air where Grotle hits it. It quickly gets back on it feet, ready to battle, when Brock calls off the match! He states that since its Cyndaquil's first battle, it should rest. Piplup then goes over to congratulate Grotle, only to see that except for Ash, everyone's attention is on Cyndaquil. Piplup becomes so jealous, that when Dawn offers it a Poffin, he jumps in the way and eats it. This results in a brawl, which only ends when Dawn tells them that if they don't stop, there'll be no dinner for either of them. The two angrily have their foreheads locked together, which Pikachu breaks up again. Khoury then realizes that Marill is missing.
Ash and friends look for Marill immediately. They come across the Valley Windworks and see Marill walk inside. The group walks inside too, but several Magnemite appear out of nowhere and attack. The group finds refuge in the security office where they wake the security guard who calls off the Magnemite. They ask for permission to look for Marill, and the security guard points to the monitors that shows every room. They then see Marill wandering around in the basement storage room and leave the guard to nap again.
The scene then shifts to Team Rocket (who has has recently encountered the Magnemite due to their puffy hair), who are carrying a long power cord which they plug into a major power outlet. James comments to Jessie that it'll take several hour to juice up. Meanwhile, the group find Marill, but Cyndaquil and Piplup have gone out still searching! Back at the power outlet, Jessie, impatient with the charging speed, pulls a switch that causes a power surge which initiates a lock down!
With the doors closed, the group is stuck inside with Piplup and Cyndaquil still outside! Pikachu then tries a Thunderbolt on the door that fails and Brock suggests they wave at the camera. This also fails as the guard is still sleeping in security. Khoury then panics, wondering if they'll be in the room forever to which Lyra comments by saying a little "positive thinking would do some good for him." Brock then spots a ventilation shaft and stack boxes and crates with Ash and Khoury. As Ash stuggles with the vent cover, the girls are standing at the opposite wall and Lyra says to Dawn that if she'll be stuck forever in the room, she would like to get married. She disregards Khoury and then asks Dawn if Ash is her boyfriend, to which she declines. Lyra asks who Dawn thinks would be the best for such a situation out of the three boys, and Dawn says that she really doesn't know. Lyra presses Dawn on the subject, but Dawn tells her that she never really thought about it. Lyra looks somewhat surprised and states that she thought it would be the first thing she would think about.
Ash then opens the shaft stating it's too narrow for him, so Pikachu goes instead to find himself right above the outside of the door. He finds Piplup and Cyndaquil still glaring at each other, to which he sighs. He comes between them and beckons them to follow. Meanwhile, while Team Rocket is searching for food, they discover the security room and see the three Pokémon separated from the group and plan to nab them. They cross paths with Pikachu and friends and begin to chase them and are greeted by Magnemite. Jessie then sends out Wobbuffet to use Mirror Coat which cause the damage to reflect back and knock them out. Back in the room Ash tries Grotle's Energy Ball, but it just bounces all over the room barely missing everyone and destroys a shelf. Lyra sends out her Girafarig to use Double Hit on the door which also fails. She then asks Khoury to try, which he responds by saying that if no one else can do it, he certainly can't. Lyra replies by saying how his negative personality drives her crazy. Ash tries himself with a crow bar and only ends up hurting his hands, so Brock suggests a break. They have a snack break and take out seven cookies realizing there are five people! Despite Khoury's accurate calculations of 1.4, Lyra states since Dawn and her are girls, they get two each (though Dawn thinks that isn't quite fair).
Pikachu then finds the security room, only to be ambushed by Team Rocket! Piplup fires a Whirlpool and Pikachu uses Thunderbolt, canceling the lockdown and sending Team Rocket running off! The Trainers and Pokémon reunite and Piplup and Cyndaquil begin fighting over Dawn's attention, so she calls Cyndaquil back to it's Poké Ball. They tell the guard they found Marill and leave the Valley Windworks on a happy evening... But suddenly, a blinding light flashes, turning out to be a giant Magcargo mecha built by Team Rocket which was being powered up by the power cord! They fire an extremely powerful energy blast that almost causes damage to the group, but because Team Rocket didn't give enough time to charge the battery, the single shot depleted their energy supply. Vulnerable, Pikachu uses Thunderbolt, sending Team Rocket blasting off and saving the day.
- During the scene where Lyra was talking to Dawn, the line on her hat was white and not pink.
- During the original Cartoon Network airing there was a quick blackout during the title screen.
- About half-way through the episode, everyone starts waving at the security cameras. The cam to the left of Ash and friends in front of the sleeping man shows some corridor. However, when Team Rocket comes into the room, the camera appears to have moved to another room, showing the corner of a corridor where Pikachu, Piplup and Cyndaquil were.
