Pikachu's Goodbye

Ash and the group stop by a river to have a quick lunch. Pikachu hears something and notices another Pikachu nearby. The other Pikachu is younger, and accidentally falls in the river. Pikachu jumps in to save it, and the two are quickly overpowered by the river. Ash tries to help, but cannot reach the two in time. Just before the two fall off a waterfall, a whole group of Pikachu arrives and pulls the two from the river. Ash's Pikachu is quickly accepted in this group. As Ash witnesses all the fun Pikachu is having, he begins to think that maybe this I where Pikachu really belongs. Meanwhile, Team Rocket decide to steal all the Pikachu instead of just Ash's in hopes they will get on Giovanni's good side.
