in Pokemon dimond its a shiny stone
No, you just have to trade it then it evolves.
No one evolves for a strange reason
It is an evolution item need for Feebas to evolve into Milotic.
This answer probraly wont help you much but, all i know about him evolving is that you need to trade him with an item. sorry i don't remember what item it was.
Yes, you can evolve Porygon in Pokémon Mysery Dungeon: Red Rescue Team but only into Porygon2, Porygon2 cannot evolve into Porygon-Z. You wil need to take your Porygon to Luminous Cave and it wil evolve as long as you have the Upgrade item and the Link Cable item.
Use a thunderstone on a picachu to evolve it
I don't think you need an item but if you do then it probally be a fire.(level up not item)
no, just trade.
easy depending on your Pokemon it may need an item for example for riolu to evolve you need an item [the place is the luminous spring].and you need to recruit palkia!
Bidoof cannot and will not evolve into Purge, no matter what you do to the poor fictional beaver. It does, however, evolve into Bibarel at level 15, with no item involved.
weavile you need the item sharp claw
Porygon doesn't evolve at a level. You need a special item to make it evolve.
You need the Link Cable in your bag and if it requires an additional item to evolve then that item too then you can evolve it in the Luminous Spring.
you have to trade it. it doesnt need a item
you need to transfer rhydon with the item ¨protector¨ and he or she evolves
