Here's a fun idea, breed two starter pokemon from grass, fire, and water (i.e. 1 charmander 1 torchic 2 froakies 2 chespins), and from i suppose vaniville town and the goal is to circle around the entire region and beat the elite four, ones who die must be deleted, you can breed more from the ones you already have
i guess it's too much like the nuzlocke challenge iunno pikmin has been on my mind for a while i'm trying this challenge out for myself to see if its feasible probably not because there's no vs seeker oh well probably a lame idea oh well well well I STILL HAVE NO SHINIES WOTS THE DEEL
