Pichu Brothers
The Pichu Brothers are a pair of Pichu who live in a big city. They were first introduced in the third mini movie Pikachu and Pichu, where they met Ash's Pikachu who was lost after falling out of a nearby building, in which Ash was planning a party celebrating the anniversary of when he and Pikachu first met. Pikachu and The Pichu Bros. went all round the town getting into trouble with a Houndour who eventually helped them when the local Pokémon Playhouse was collapsing.
They appeared again in the fifth mini movie Camp Pikachu and the Pokémon Channel special episode Pichu Bros. in Party Panic as well as several Chronicles episodes.
In Camp Pikachu they had an adventure where they were lost a long way from home after a train ride, however thanks to Pikachu, the rest of Ash's Pokémon, and a Wynaut, they were able to catch a train back home again.
In Pichu Bros. in Party Panic, Meowth was going to throw a party, however the Pichu Brothers and their friends hadn't recieved an invitation. So they go on a quest to find one, in the end you find that an Azumarill had their invitations all along and hadn't gotten around to delivering them yet.
