What do you have to do to get a nincada to evolve into a shedninja,a gloom..

To get Shedinja, have 5 Pokemon in your party and make your Nincada evolve, you must also have the pokeball you used to catch your Nincada in your bag.

To get Belossom, use a sun stone on Gloom.

1. You don't evolve Nicada into Shedinja. Why does everyone think that? Sigh... Another repeated question. Well, have a Nincada in your team. Make sure that you also have an extra poke ball and an empty space in your team. Evolve Nincada into Ninjask at level 20. He should learn four new moves, just so Shedinja has some moves. Anyway, using the extra pokeball, Shedinja, which is the shedded skin that came from Nincada when he evolved, will be caught and placed in the extra slot in your team.
2. Well, simply put, use a sun stone on Gloom.
3. Where did Polywhirl come from? Traded him from FR/LG? Anyway, trade him while he's holding a King's Rock.

To get a shedinja you have to have a nincada first, have a empty slot for a empty Pokemon then you raise it to level 20 (dont pass it) after it evolves look at you Pokemon and you should have a shedinja.and to get a bellosom you need a gloom and a suns stone then evolve it to get a polytoad you need a kings rock give it to him and then trade with someone else they should have the polytoad and then trade it back to you.

Hope I helped

For Shedninja, make sure you have a empty spot in the party and 1 pokeball. It will make it on level 20. To get Bolossum, give a second level from oddish to hold Sun Stone and trade it. To get Politoed make Poliwhirl hold Kings Rock and trade it.

I only know one o get shedninja when your nincada evolves have at least on peokeball in your bag and an empty slot in your party when it evelves you have nijask and shedninja

Nincada does not evolve into a shedinja, when it's evolving, it sheds making a new pokemon. So if you catch a nincada, you get 2 Pokemon 2nd pokeball free!

Have one empty slot in your teamwhen nincada is evolving at lv20+.

To evolve nincada into a shedinja, you need a free space on your party and a pokeball in your bag,then evolve nincada.
To evolve gloom into a belossom, use a sun stone on gloom.

I forgot how to get a polytoad.

Nincada doesn't evolve into Shedinja, but if you have another make of Ball in which you caught the Nincada and have a party space open when you evolve it, Shedinja will appear in that space. Gloom evolves into Bellossom when exposed to the Sun Stone, and Poliwhirl evolves into Politoed when traded with King's Rock attached.

Well, to make a nincada evolve into a shedinja,have at least 1 pokeball in your bag, and 5 Pokemon with you(including your nincada). To get a gloom evolve into a bellossom, use a sun stone. And, to evolve poliwhirl into politoed, trade while it's holding a king's rock.

Git-R-Dun!!!!!

I forgot the other two. Gloom evolves into a blossem with the sun stone, and polywhirl into polytoad when traded holding the king's rock.

nincada doesnt evolve into shedinja. kay this is what you do.have a free space in your party and at least one pokeball that you caught th ninada with in your bag.evolve it into ninjaskand it will want to learn three new moves.teach it all three moves and when you are done shedinja should appear in the empty slot in your party.

Does it have to be a regular Pokeball, or will any work?
