same way you caught tapu koko! only, i didn't "re-do" everything for each one, no i just battled each one when i arrived at there spots and caught them!
this is ash's Pikachu he just died 2 weeks ago so after that i found Pikachu and then Pikachu and me set out to be Pokemon masters he satyed with me because i took care of him and i also dont want to Evolve him he wants to get stronger as a Pikachu same for Snowy she wants to stay a Vulpix because she is afraid to Evolve from this Ice stone *show ice stone to Meme* you should also do the island challenges so you can use Z-MOVES LIKE US
(Pikachu&Snowy)PIKA/VULPIX!
