The player can place up to ten Poké Snacks on the tray present at each of the three Poké Spots to attract wild Pokémon to the location. The player's P★DA will tell the player how many Poké Snacks are present at each Poké Spot at any given time, as well as alert the player if a wild Pokémon has been attracted to them. The more Poké Snacks present at a Poké Spot, the longer the wild Pokémon will stay there. Once all the Poké Snacks have been eaten from the tray, the wild Pokémon will leave. The player can also remove Poké Snacks from the tray and return them to their Bag.
Occasionally, a Munchlax belonging to the Herbalist from Gateon Port will appear and eat the player's Poké Snacks instead. In case of such an event, the Herbalist will appear and make up for the lost Poké Snacks by giving the player ten new ones, regardless of how many Munchlax had eaten.
After the Bonsly on S.S. Libra has run away, it may appear in place of a wild Pokémon at a Poké Spot with Poké Snacks in it. If the player approaches Bonsly slowly enough, they can capture it and return it to its owner at ONBS. If they approach it too fast, it will run away.
The Poké Snack cannot be held. This is to prevent it being held by a Pokémon traded to the core series games, where the item does not exist.
