In Pokemon Pearl, how can I get one of my Pokemon to stay outside of his pokeball

Um.. you could do it in a place called Amity Square. It's located north of Hearthome city. Only cute pokemon will be allowed inside. Pokemon like Pikachu, Pachirisu, Jigglypuff, Clefairy, Psyduck, Torchic, Shroomish, Drifbloom, Happiny, Skitty, and Buneary are allowed. You could get TM 45 there and a spooky plate ( for Arceus )

there. Also, every 200 steps, you could get a contest-related item. Just pick it off your pokemon. Hope this helped xD

You can in amutiy sqaure you have to have a (cute) pokemon and pokemon comes out of the pokeball then walks behind you!

u cant. they lied. the only time a pokemon can follow u is pokemon yellow. it never happened before in any pokemon game execpt when u go to pokemon park but that is for only some pokemon

You cannot have a pikachu follow you around during normal gameplay, but if I remember correctly you can have a cute pokemon follow you around in a park in one of the cities. Maybe that's in Diamond and Pearl. I can't remember. Hope this helps. :)

I think you mean in the pokemon park they have but not walking around in the game only in the park and its for surtin pokemon

You can bring out a Pokemon only when you go underground

i dont think there is a way to do that.

theres only been one game where a pokemon folows you and thats yellow version for GBC.

But if there is a way then keep tryin!

Good luck!

you can't, you have to be in the pokemon park and can only have certain pokemon.
