Some Enchanted Sweetening! (Japanese: ハクタイの森！ミノムッチ進化作戦！！Hakutai Forest! The Minomutchi Evolution Plan!!) is the 30th episode of the Diamond & Pearl series, and the 496th episode of the Pokémon anime. It first aired in Japan on April 19, 2007 and in the United States on September 29, 2007.
Ash and his friends find a tree full of delicious honey, the scent of which has attracted several Pokémon, including Ash's Aipom and a wild Burmy. The Burmy has also attracted the attention of a Trainer, Cheryl, who captures it with her Chansey. Cheryl is a treasure hunter in search of the Enchanted Honey that's said to lie within the Amber Castle. But to find it, she needs a male Burmy she can evolve into Mothim, which has an amazing sense of smell.
Ash offers to help evolve Burmy by letting it battle Turtwig. It should be easy for Burmy to beat a Grass-type, but this Burmy isn't very robust! It loses the match and gets seized by Team Rocket as part of a nefarious plot to evolve it into Mothim and impress Giovanni. After Team Rocket makes their getaway with Burmy, however, they discover that Burmy's better at eating all their food than it is at battling.
Just in time, Cheryl and our heroes arrive to rescue Burmy. Burmy manages to help rescue itself by teaming up with Chansey to defeat Meowth and Wobbuffet, and it finally evolves into Mothim! The stage is set for everyone to join forces and send Team Rocket blasting off. That's not all—Mothim then picks up a scent and leads Ash and the gang towards a new chapter in the search for the Amber Castle!
Ash and his friends are traveling to the Eterna Gym. They get to the Eterna Forest, and see a woman trying to catch a Burmy. She is using a Chansey, who uses Attract. Burmy is Attracted, and she seems very happy. Ash and Dawn comment that you have to attack a Pokémon to make sure you catch it. The woman takes their advice and Chansey uses Double Slap. Burmy uses Protect, but Chansey uses Egg Bomb, and the woman throws her Poké Ball. She catches the Burmy. She thanks Ash and Dawn, and tells them that she has three Wormadam. She throws their Poké Balls, and they come out to confirm what she said. She says that all her Burmy were females. Ash inquires why she wanted a male. She tells them she wants the end result to be a Mothim. Ash asks why again. The woman tells them her name is Cheryl, and she is a treasure hunter. She says she wants to fill in the empty space in her grandfather's collection of treasures, and needs just a bit of the Enchanted Honey, which is sweeter than any other honey. They say that they'll help.
Cheryl takes out her Burmy and tells the Wormadam to cheer him on. Ash takes out his Turtwig and tells it to go easy on Burmy. Burmy starts out with a Tackle, but it bounces off Turtwig. Dawn and Brock comment to themselves that the Burmy must be very weak, since he is supposed to have an advantage against Grass-type. Turtwig uses Tackle back, and Burmy is thrown back. All his leaves fall off, and two cover Turtwig's eyes. Turtwig panics, and it accidentally tackles Burmy, who loses. Dawn says that Turtwig is being a little rough, so Ash calls it back. He calls out Pikachu. Pikachu uses a small Thunderbolt, which Burmy takes weakly. Cheryl tells Burmy not to give up, and use Tackle. Pikachu doesn't dodge it, and pretends to be damaged severely. Then Team Rocket comes. They fly off with Burmy, to try to get him to evolve. Ash calls out Staravia to search for Burmy. He circles around where Team Rocket and Burmy are.
Meanwhile, Team Rocket sends out Seviper and Carnivine. Burmy loses, and Jessie shakes Burmy hard. James tells her to stop scaring the poor Pokémon. Burmy says that he's too hungry to battle Meowth, who translates. Once he's fed, Meowth battles Burmy and wins. First, they're all happy they won for a change, and then get mad at Meowth for winning.
Then, Ash and his friends arrive, and start battling Team Rocket. It's 4 or 5 on 5, when Burmy evolves into Mothim. Team Rocket try to take off with him, but Ash doesn't let them get away. They blast off. Then, all is well until Mothim picks up a scent. They all run after Mothim, and the episode ends.
The English dub title is a pun on the song "Some Enchanted Evening" from the musical South Pacific.
This episode has a lot in common with a previous episode, The Problem with Paras, in the sense that both revolved around a woman who needed help evolving a Bug-type Pokémon, so Ash had his Pokémon lose a battle against her on purpose. Unlike before, however, none of his Pokémon refuse to do so out of disobedience.
For reasons unknown, the boss fantasy is removed from the dub. It has been widely speculated that the scene was removed due to the extremely suggestive shot of the Pokémon rubbing up against and licking Giovanni, who is wearing only swim briefs.
