This is one of the few episodes storyboarded by executive producer Kunihiko Yuyama.
Setting the World on Its Buneary! (Japanese: ミミロルとあそぼう！？Let's Play with Mimirol!?) is the ninth episode of Pokémon the Series: Diamond and Pearl, and the 475th episode of the Pokémon anime. It first aired in Japan on November 16, 2006 and in the United States on June 18, 2007.
When Dawn wakes up to a bad hair day, there's only one solution: have Piplup use Bubble Beam to fix her hair! Yep, it's just another typical morning on the road for our heroes until Pikachu catches the eye of a wild Buneary. Dawn wants to catch it for the upcoming Pokémon Contest, but it's too shy to stick around for long. And when Buneary comes back, both Ash and Dawn want to catch it, but Buneary's too slick for Piplup to handle. That means Ash and Pikachu get a chance!
The only problem is, Buneary definitely has a crush on Pikachu and even hits our heroes with an Ice Beam so it can be alone with Pikachu. This is certainly a new situation for Pikachu, who isn't entirely sure what to do! But when Team Rocket jumps in and steals Buneary, Pikachu bravely offers to go with Team Rocket if they let Buneary go. Team Rocket being Team Rocket, they accept Pikachu's offer and then keep both Pokémon anyway. Pikachu manages to break free and rescue Buneary, and the two then work together to wreck Team Rocket's latest Pokémon-stealing robot.
After seeing all this, Ash and his friends agree that Buneary would be a great addition to the team. However, Dawn decides to observe proper Trainer etiquette and battle it first. This time Dawn and Piplup are prepared for Buneary's moves, including Dizzy Punch, and it's a successful catch! Now Dawn has a new Pokémon up her sleeve for the Pokémon Contest in Jubilife City!
At sunrise, Dawn screams and wakes up a flock of Starly. Nearby, a familiar set of ears perk at the sound. Brock is preparing breakfast, as Dawn's protests wake Ash. He rushes to Dawn's tent, but she tells him to keep out because her hair is messy. Dawn tries to fix her hair manually, but it doesn't work. Piplup is amused, and Dawn gets the idea to use Piplup's Bubble Beam. Ash is puzzled at the order. Brock drops a potato and Croagunk simply looks at it. He eventually tosses it forcefully upward. Ash backs up and trips into Dawn, while Pikachu grabs the potato. The capture impresses a nearby wildBuneary.
Meanwhile, everyone finds out about Dawn's fixed hair. Ash is puzzled by the method. Dawn wants to use the method to fix Ash's hair, but he mentions that he has his cap. At that word, Aipom steals Ash's hat and runs away with it. Pikachu pursues and steals it back with a Quick Attack. However, the hat covers Pikachu's face and he lands in the middle of a path. Officer Jenny almost runs over Pikachu, but Buneary jumps in and gets Pikachu out of danger. Ash reclaims his hat and Dawn catches up, noting the Buneary.
Buneary seems shy, covering her face with her fur. She bounces away, slamming into a tree before escaping. Jenny scolds Pikachu, and Dawn confuses her for the same Jenny in Sandgem Town. Brock shows Dawn that each Jenny is different. Brock is infatuated as usual, but Croagunk calms him with Poison Jab and drags him away. Jenny shows Ash and Dawn a picture of a disguisedTeam Rocket, involved with stealing machine parts, but they don't recognize them.
Later on, everyone's eating lunch, and Ash decides to catch the Buneary next time, but Dawn protests because she still needs to catch a Pokémon, mainly for her first Pokémon Contest. Team Rocket is nearby watching, and while James is working on a machine, the others notice Croagunk is with them. Croagunk stops eating and notices something in the bushes. Buneary jumps out and bounces away. Ash and Dawn pursue, leaving the dishes to Brock.
Dawn takes the lead and has Piplup attack Buneary with Bubble Beam, taking the first opportunity. Ash lets her go first. Piplup misses with Peck, but attacks with Bubble Beam. However, Buneary's Ice Beam freezes the attack, stunning everyone. Buneary uses Dizzy Punch to knock Piplup down. Buneary seems to be trying to impress Pikachu, and Piplup is now confused. Dawn doesn't know how to treat the condition until Brock tells her to recall Piplup. But before she can do so, Buneary knocks out Piplup with Bounce.
Dawn recalls Piplup and lets Ash take his turn. Pikachu gets ready to battle, but Buneary acts differently, not willing to attack. They finally notice Buneary is attracted to Pikachu. Ash tries to throw a Poké Ball, but Buneary freezes everybody with Ice Beam, though Starly escapes the blast. Buneary dances with Pikachu, spinning and whisking him away.
Pikachu finally frees himself and scolds Buneary for freezing Ash and his friends, upsetting her and making her cry. Pikachu tries to remedy the situation but he fails. Starly catches up and notices. Buneary suddenly stops crying, ears perking up at something. Suddenly, a glass ball captures Buneary, locking her into Team Rocket's mecha. Starly flies away while Pikachu attacks with Thunderbolt. However the Electric-typeattack is diverted to hurt Buneary. Croagunk finds the frozen group and uses Poison Jab to free them. Starly arrives and leads the group to Team Rocket. Pikachu decides to surrender against Team Rocket, and they don't hesitate to capture Pikachu into another glass capsule. Pikachu orders them to release Buneary, but they refuse. Ash and the others find Team Rocket. Buneary tries to free herself with Dizzy Punch but it fails, and Pikachu uses Iron Tail to try to escape. Ash tries to rush over, but Team Rocket blocks him. Jenny arrives and connects Team Rocket as the factory thieves. Pikachu frees himself as Team Rocket detaches a part of the mecha, lifting off with rocket propulsion. Pikachu frees Buneary with Iron Tail. Buneary use Ice Beam and Pikachu uses Thunderbolt to send the pod plummeting. The Pokémon jump off the falling pod. Ash catches Pikachu and Dawn catches Buneary. Jenny tries to arrest Team Rocket, but they run away, with Jenny in pursuit.
Buneary is drawn to Dawn, but Dawn needs to battle her again for an actual catch. She summons Piplup again, leading with Bubble Beam, but Buneary dodges. Piplup tries to evade and use Peck, but Buneary dodges again. Piplup's Bubble Beam and Buneary's Ice Beam is even. Buneary attacks with Dizzy Punch, but Piplup dodges and uses Peck successfully. Dawn throws a Poké Ball to catch Buneary, and after a few moments, it succeeds. Buneary becomes Dawn's first catch and she celebrates. Everyone congratulates her and she lets Buneary back out. Now Dawn is ready for the Jubilife Contest.
Interestingly, when Aipom stole Ash's hat in the episode, Ash reacts in a similar manner to when Mankey stole his hat in Primeape Goes Bananas, even though he acted more mature the first time Aipom stole his hat.
In the first airing of the dub the title card has a typo, using it's instead of its.
This, however, was fixed for the home video release, reruns and streaming releases.
In one scene where they saw Piplup dizzy, Pikachu is standing right next to Ash; however, in the next scene, Pikachu is now on his shoulder.
When Ash gets out of bed and stands next to the tent, he is barefoot. After he crashes into Dawn, he is wearing his shoes.
