There have been reports that Pokémon are being tormented by nightmares in some areas of Greengrass Isle. Upon investigation, it has been discovered that this is caused by the Mythical Pokémon Darkrai’s power to induce nightmares. To rescue the Pokémon, we need the Legendary Pokémon CresseliaThere have been reports that Pokémon are being tormented by nightmares in some areas of Greengrass Isle. Upon investigation, it has been discovered that this is caused by the Mythical Pokémon Darkrai’s power to induce nightmares. To rescue the Pokémon, we need the Legendary Pokémon Cresselia’s cooperation. Cresselia’s ability to induce pleasant dreams combined with Snorlax’s Drowsy Power can help us dispel Darkrai’s nightmares!
Outline
This two-week event is a special period where Cresselia shines against Darkrai. During the event, the Legendary Pokémon Cresselia is more likely to appear, and a bonus will be applied to Drowsy Power if you have Cresselia on your team when you sleep.
Additionally, you can obtain samples of Cresselia Down during the event through sleep research. You can trade these samples via the Event Exchange for new items—Cresselia Incense and Cresselia Biscuits—to help you discover Cresselia’s sleep styles!
Furthermore, during the event, the average Drowsy Power of researchers worldwide and your own Drowsy Power will be combined to accumulate Event Drowsy Power. This Event Drowsy Power may be the key to dispelling Darkrai’s nightmares!
We encourage you to collaborate with researchers worldwide to dispel Darkrai’s nightmares and rescue the Pokémon!
And…if you make good progress during the event, there might be a chance to befriend Darkrai…?
We hope you’re looking forward to this!
