You catch raikou in vermilion city in the smallest patch of grass
They, like any other animal simply hide in the grass. Entie, Suicune and Raikou. I found all of them in the grass but they all run away. I think you need a master ball. I hope you find this helpful!
yes
both
yes they do
you can get raikou in the grass. trust me i am 100% sure [all over johto]
grasshopper's live in grass because they camouflage in the grass. they do that because the grasshopper's hide from there prey. :)
Because they like to hide
Raikou can be found anywhere where grass is the best route would have to be route 1.
No it will appear in the grass anywhere on the routes try route 1 it comes there often.
You can find them anywhere around the routes of kanto so look in the grass.
yes but you must get them on the pokedex first.(see them in the wild) then press start and if they are in the same route go into the grass to catch it.
