Pokemon Black & White Episode 12 Here Comes the Trubbish Squad

On their way to Nacrene City, the gang is harassed by a group of schoolchildren with the Garbage Pokémon Trubbish. They head to a nearby Pokémon Daycare and kindergarten, where they learn from the kids' teacher Miss Daniella that the kids found the Trubbish at the garbage dump and decided to bring it back to the school. However, Miss Daniella told them that the Trubbish could not stay and brought it back to the dump, only for the kids to bring it back and form a gang called the "Trubbish Squad" and barricade themselves in a treehouse rounded with a wall of trash. Ash goes up to the treehouse to convince them that the Trubbish has to go, but is attacked by the group yet befriends them as well. Elsewhere, Team Rocket is given a fake meteorite from Flint and are told that they will get more information later. Back at the school, the Sandile with sunglasses arrives and the children have Trubbish fight it. Miss Daniella then decides that she should battle the Trubbish Squad to determine whether or not Trubbish should stay. Ash challenges her, as he has joined the squad, and she sends out her Deerling to fight Pikachu. The fight causes the trash wall to collapse, almost crushes one of the kids and Trubbish; however, Ash, Miss Daniella, and the others save them by holding the wall back. After the fight, she decides that Trubbish can stay and everyone cleans up the school. Before Ash and his group leave, the owner of the Daycare gives Ash a Pokémon Egg.
