There are two various forms of Shellos, these are given as;

• East Sea
• West Sea

Players are required to hunt down both of them in order to fulfill the task proposed in Pokémon Legends: Arceus.

The story quest also known as the new mission is the key for unlocking the request for the Shellos of East and West. In Jubilife village’s clothing store, Anthe, the merchant will state that looking at two unalike colors of the Pokémon will be her inspiration for designing new styles of clothing pieces. Here, you will be assigned with the quest of discovering Shellos of two dissimilar colors.

In Cobalt Coastlands locate the Seagrass Haven or Tranquality Cove, head down in its direction to recover the East Sea Shellos. They are characterized by the blue and green tint on their skin. They are conveniently located in the middle of the map, north of Sand’s

The step will be followed by the journey towards Obsidian Fieldlands to Ramanas Island or Sandgem Flats. After looking around, you will spot a pink and brown West Sea Shellos. The Sandgem Flats in the southwest are where you can locate them the simplest.

Fortunate enough, Shellos exhibit friendly behavior so capturing them won’t be of much struggle. After catching both East and West versions bring them to Anthe. Your quest will be completed afterwards. In return you will be rewarded with opening of various new options in her shop. Bonus point: you can keep both of the two Shellos you hunted for.
