To play Iris's Eyes scenes, you need Butterflies. Each round you play costs ten Butterflies and you can collect them by either playing Hidden Object Scenes in Pearl's story (where they're awarded to you randomly) or by purchasing them directly from the Butterfly Store for in-game Cash. Currently, not all players have the Butterfly Store available in their game, so if you don’t have the option to purchase Butterflies just yet, please keep an eye out for an announcement through our official Pearl’s Peril’s Facebook page.
