To bring in Scent Sachet and Chantibonbon Sword and Shield Pokémon, you will need battle points. These can be earned at the battle tower. When you have collected 20 battle points, you will have enough to buy Sachet Senteur and Chantibonbon.
From there, head to the Pokemon Center in Hammerlocke. Go to the Pokémon Center where you spawned after using Fast Travel, then talk to the Battle Points Shop trader in the black and white sports outfit on the right side of the Pokémon Center.
She will sell you a Senteur Sachet for 10 battle points and a Chantibonbon for 10 battle points. You can use Chantibonbon to transform Sucroquin into Cupcanaille by giving them the Chantibonbon, then trading the Pokémon to someone. It will then become Cupcanaille, and they can resell it. Keep in mind, Sucroquin is an exclusive Pokémon Sword.
Sachet Senteur will allow you to transform Fluvetin into Cocotine. The method is similar and you have to give the pannier to the Pokemon and then trade it with someone to evolve it. Fluvetin is an exclusive Pokémon Shield.
Although Fluvetin is exclusive to Pokémon Shield and Sucroquin to Pokémon Sword, they both appear in the same places in both games. You can find these Pokémon at the following locations:
- Route 5
- Glimwood Entanglement
- The Giant's Mirror
- Stony Wilderness
- Max Raid Battles
The best way to do this is to find someone who has the version of the game you don't have and trade with each other so you can both get the evolved forms of each Pokemon. You will both need two exclusive The Pokémon and two Sachet Senteur or two Chantibonbon to be sure to be able to obtain the evolved forms of the Pokémon.
