ash and friends are in the forrest taking a break and having a good time when they run into a bunch of wild pikachu which ash’s tries to get along with but the pikachu reject him because of having a trainer until ash’s rescues one of them from going over a waterfall (Ash’s originally gets along but they scared off by ash) with help from the wild ones. team rocket spot the pikachu and want to steal them. that night ash’s pikachu is welcomed into the pack with ash and friends watching from a distance and are quite happy brock makes acomment that its best for pikachu to be with his own kind which has ash worried. at this point team rocket try and steal the pikachu with a net but fail as usual as the pikachu bite their way out of it and team rocket have their usual fate. ash at this point considers leaving pikachu with the wild ones despite misty and brock and pikachu tryirng to convince him otherwise and ash keeps pikachu especially after a show of support from the wild ones.
next time a trainer abandons an eevee and an evolution party.
