Friend Incense is an item that causes at least one of the Pokémon that came to sleep to be hungry during snack time after your sleep research. If you give a Poké Biscuit to a hungry Pokémon, it’s guaranteed to be a big hit or a mega hit. You can set up your incense on the stump by your tent, or through the pop-up that appears when you tap the Sleep button. Try using it when you want to befriend Pokémon!
