BW020: Dancing With the Ducklett Trio!

is the 20th episode of Pokémon: Black & White.
==Synopsis==
During a lunch break, our heroes are shocked when the ground suddenly falls out from under Ash and Pikachu, sending them sliding through a long underground tunnel! At the end of the wild ride, Ash and Pikachu come face to face with an old friend, the Sandile who wears sunglasses. It appears that Sandile has traveled a long way to challenge Pikachu to a rematch!
Their battle is quickly interrupted by a mischievous Ducklett who wanders out of the bushes. It turns out this Ducklett is part of a thieving trio, and one by one, they steal Cilan’s serving dome, then Sandile’s sunglasses, and finally Ash’s hat! Retrieving these items proves to be a formidable task, as the three Ducklett have some tricks up their feathery sleeves!
Sandile and Pikachu team up to take on the three Ducklett. During the fray, Pikachu learns a new move—Electro Ball! The powerful zap sends the thieves on their way, and our heroes are able to retrieve their stolen items.
Sandile and Pikachu get back to their original plan and resume their battle—which ends with Sandile evolving into Krokorok right before Pikachu’s Electro Ball sends it flying! Ash plans for another rematch next time they meet Krokorok, and our heroes resume their much-sidetracked journey toward Castelia City and Ash’s next Gym battle!
==Episode plot==
Scraggy and Axew face each other. Scraggy uses Headbutt, hitting Axew, who scratches it back. Scraggy leers Axew, who uses Dragon Rage. Cilan already protects his food, as Axew's attack explodes. Iris sees they tried, at least. Cilan invites everyone to lunch. Oshawott comes out of his Poké Ball, so Ash goes to send his remaining ones. However, he falls down a tunnel, which closes in. Cilan sends Pansage, while Iris goes to send Excadrill, as this is a moment it has to obey her. The Sunglasses Sandile dug out the tunnel and jumps out, while Ash and Pikachu fall down from it.
They see the Sunglasses Sandile, who dug out the hole. Ash senses Sandile did that to battle Pikachu, so he allows them to do that. Iris sends Excadrill and orders it to find Ash and Pikachu. Excadrill is still sealed, so Iris calls it back. Suddenly, Cilan encounters a Ducklett, who steals his dining bell. Cilan goes after it, though it uses Scald, which hits Oshawott and Iris. Ducklett moves away, so everyone chases it. Pikachu uses Thunderbolt on Sandile, who is not affected, as Sandile is a Ground-type Pokémon. Sandile goes to bite, but gets hit by Iron Tail. Suddenly, a Ducklett appears on the battlefield.
Ash warns Ducklett they are in a middle of a battle. Sandile tries to push Ducklett away, who peeks in its mouth, then tickles Sandile's nose. This causes Sandile to blow its nose, causing its sunglasses to be put onto Ducklett. Sandile is very sad and wants the sunglasses back. However, Ducklett uses Water Gun, pushing all of them away. Ducklett laughs at them and flies away. Ash promises Sandile to get the sunglasses back. As they travel, Ash and Sandile encounter some Woobat. Sandile gets scared, but Ash points out those were just Woobat. Suddenly, a Ducklett appears, snatching Ash's hat. Ash orders Ducklett to give back the hat, who uses Ice Beam, laughs and flies away. They follow it and encounter Ducklett with Sandile's glasses. Pikachu uses Thunderbolt, hitting both Ducklett.
However, a third Ducklett appears, who uses Wing Attack, stopping Ash and Pikachu. The Ducklett uses Scald on Ash, followed with Ice Beam. The Ducklett laugh, though Sandile bites the ice away, freeing Ash. Pikachu goes to use Thunderbolt, though the Ducklett hide in a hollowed tree and throw junk at Ash, Sandile and Pikachu. Pikachu uses Thunderbolt, though the Ducklett throw an umbrella, causing Pikachu to electrocute the object. Ash and Sandile remove the umbrella, only to find Pikachu exhausted by his attack. Ducklett use Scald, so Ash, Pikachu and Sandile run away from them. Iris finds Scraggy, Axew and Oshawott, telling them not to run off. She proposes to go back, but Cilan came out of the hole to her, so Iris knows Ash and Pikachu came out here.
As Ducklett play around with the junk, Ash still promises Sandile to get the sunglasses and the hat back. Ash and Sandile approach the Ducklett, telling they do not want to fight, instead they want to get their stuff back. Ducklett approaches Ash, who is ready to take the sunglasses. However, Ducklett uses Water Gun, annoying Ash, who goes to battle. Pikachu goes to use Thunderbolt, but is unable, as he hit himself under the umbrella. Sandile goes to battle instead, while the Ducklett remove their stuff. Sandile uses Stone Edge, though Ducklett dodge. Ducklett use Ice Beam and Scald, but miss. The third one uses Water Gun, but Pikachu's Iron Tail counters the move. Pikachu goes to attack, though Ducklett dodge and use Wing Attack on Sandile. Ash and Pikachu charge in, attacking the Ducklett.
Suddenly, Pikachu radiates electricity, as he learns Electro Ball and releases it on Ducklett, blasting them off. Iris and Cilan appear and saw Pikachu's Electro Ball. However, the Ducklett appear once more to get revenge, who attack the heroes and manage to hit Oshawott with Scald. Pikachu uses Thunderbolt, blasting the Ducklett off again. Ash, Cilan and Sandile retrieve their stuff back. Later, Pikachu and Sandile are healed at the Pokémon Center. Nurse Joy knows the Ducklett are known for making trouble, but Ash is grateful, for Pikachu learned a new move. Later, Sandile faces Pikachu, though Iris and Cilan do not understand why would it do that. Iris wonders if Pikachu is at a disadvantage, though Cilan feels Ash has a trick.
Sandile uses Stone Edge, hitting Pikachu, who uses Quick Attack. Pikachu uses Iron Tail, though Sandile digs and hits Pikachu. It does so once more and has enough experience to evolve into Krokorok. Krokorok uses Stone Edge, but gets reflected back with Electro Ball, causing Krokorok to blast off. Iris and Cilan admit Electro Ball is an amazing move, while Ash promises to defeat Krokorok once he sees it.
