Minccino-Neat and Tidy! (Japanese: チラーミィはきれいずき！？ Minccino is Clean!?) is the 13th episode of Pokémon: Black & White.
As the heroes continue the journey, a lass comes to meet them. However, she trips over a stone, loses balance and knocks Ash and Cilan into the river. The lass apologises to Ash and Cilan, who dry their clothes. The lass shows on her communicator Prof. Juniper, who greets Ash. Juniper remembers she did not give Ash a Badge Case, so sent the lass, Bianca, to give it to him. The heroes introduce themselves to Bianca, who searches through her bag to find the case, but cannot find it. After Ash and Cilan put their clothes on, Bianca finds the case, but it is dirty. Ash takes the case and puts the badge in. Cilan and Iris remind Ash when he has all eight badges, he can participate in the League.
Bianca goes to see the badge, but something takes it away from her hands and runs off. The heroes go after it, but the Pokemon is too fast, though Bianca admires this Pokemon. Ash goes to get the badge, so Bianca tells he could get a replacement. Ash is angered and falls down the log, but stands up and replies he remembers the battle by seeing that badge. The heroes watch that Pokemon, Mincinno, cleans up the badge case. Ash goes to take it, but Bianca wants to catch Mincinno, sending Pignite to battle it. Pignite goes to tackle, but misses. Pignite uses Flame Charge, but Mincinno avoids and climbs up to a tree. Bianca and Pignite are annoyed, but will get the case back.
Mincinno closes its ears and releases Hyper Voice, affecting Pignite. Mincinno tickles Pignite, so Bianca calls it back. Ash goes to use Pikachu to attack Mincinno, but Oshawott comes out. Bianca is thrilled Oshawott came on its own out. Oshawott goes to tackle, but Mincinno dodges. Bianca orders Hydro Pump, confusing Oshawott, as it does not know that move. Instead, Oshawott uses Razor Shell, but Mincinno climbed up to a tree. Mincinno jumps and tickles Oshawott, then hits him with Double Slap, defeating him. Mincinno takes the case and goes away. Ash thinks Bianca talks too much, allowing Mincinno to retreat. However, Bianca asks for his help in catching Mincinno, as he needs to get the case back. Ash sees he has no choice, though would like to go to Nacrene City. Cilan tells it is just over the mountain and will not take too much time getting there.
In Nacrene City, Team Rocket studies the city's prints and decide to go to the museum for an escape route. The heroes try to find Mincinno, but Bianca has an idea and asks for shiny objects. Cilan gives her a spoon, but is disappointed, as she rubs it in the dirt. Later, Bianca set up a trap and when Mincinno comes, she would trap him under the bell. Mincinno comes and cleans the spoon, so Bianca traps it. However, Mincinno walks away, under the bell. Ash sees they have to battle and has a way to bypass Mincinno's Tickle. Ash sends Snivy, challenging Mincinno to a battle. Iris and Cilan wonder what Pokemon Bianca has. She replies she only has Pignite, disappointing them. Bianca admits she got training at home, though her father didn't want her to travel too much. Still, she got two badges already.
Snivy uses Attract, but Mincinno dodges the move. However, Mincinno uses the same move, causing Snivy to be charmed by Mincinno. Ash calls Snivy back and sends Pikachu. Pikachu starts with Iron Tail, which Mincinno dodges. Pikachu uses Quick Attack, tracking Mincinno. Pikachu uses Iron Tail, which collides with Mincinno's Double Slap. Mincinno releases Hyper Voice, blasting Pikachu with the sound. Mincinno uses Tickle, but Pikachu endures the move, causing Mincinno to be exhausted. Bianca orders Zap Cannon, but Pikachu can't use that move. Instead, Pikachu uses Thunderbolt, hitting Mincinno. Bianca goes to catch Mincinno, but cannot find the Poke Ball. When she gets it, Mincinno comes and cleans it up. However, this causes the Poke Ball to hit Mincinno, so Bianca catches it.
Cilan sees the Mincinno's talent and Bianca's personality will be a good combo. Bianca is glad she caught Mincinno. Ash takes the Badge Case, but falls down and the bell falls on him, but is unhurt. At the Pokemon Center, Nurse Joy healed Bianca's and Ash's Pokemon. Also, she checked the egg and it is healthy. Ash tells Bianca he does not know which Pokemon it is, but Bianca challenges Ash to a battle, who accepts. Bianca sends Pignite and wants Ash to send Pikachu. Ash does that, though Pignite uses Take Down on Pikachu. Pignite uses Heat Craft, hitting Pikachu heavily. Pignite uses Flame Charge, so Pikachu uses Volt Tackle, colliding with each other. After the attack, Pignite is defeated.
Bianca calls Pignite back. She comes to Ash and lets him know the next time they will meet, her Pignite and Mincinno will be stronger. She bids farewell and goes away. Iris and Cilan see she can move a lot, but Ash knows he will battle her one day.
