How to Catch Stufful in Pokémon Sun and Moon

Purchase Pokéballs at a Pokémart. Stufful's catch rate is slightly higher than average, so a few Great Balls should work well (however, be sure that you bring multiple Great Balls with you, in case your first attempt at catching Stufful is unsuccessful). You can also bring a few Quick Balls with you if you'd like to attempt to catch Stufful immediately when the encounter begins.

Bring Fighting, Flying, Psychic and/or Fairy-Type Pokémon with you. Since Stufful is Normal and Fighting-Type, it is weak to those types of Pokémon. Stufful is immune to Ghost-Type Pokémon, however, unless it is holding a Ring Target. Fire-Type moves that do not make contact are also Super Effective on Stufful if it has the ability Fluffy.

Know where to find Stufful. In Pokémon Sun and Moon, you can find Stufful on Route 8, as well as in the Akala Outskirts. It does, however, have a relatively lower chance of appearing in both locations, so you may be looking for awhile. However, eventually, you should encounter a Stufful.

Lower Stufful's health to about half or less. This will make catching it easier. Try using Fighting, Psychic, Flying, and/or Fairy-Type Pokémon, as mentioned earlier. You can also use the move False Swipe, since this move is guaranteed to leave the Pokémon it is used on with at least 1 HP. Try and avoid using moves that Poison or Burn, since this will make Stufful slowly lose health, and it may end up fainting before you are able to catch it. Stufful's level will likely be in the late teens or early 20s, so keep this in mind when choosing Pokémon to use in your encounter with it.

Throw a Pokéball to catch your Stufful. Once Stufful's health is half or less, throw a Pokéball. Eventually, you should successfully catch the Stufful, and you can add it to your party if you'd like.
