Pixies are creatures that appear when the Beautiful Sakura Bloom event starts. Tap pixies several times to chase them away, and you can get the butterflies needed for a mini-game during the Beautiful Sakura Bloom. To lure a pixie, you will need a special building—Pixie Bait. Tap few times on the lured pixie, and with some probability, you will get butterflies. You can also lure extra pixies by using the Pixie Well building.
