Halloween Event 2017

The Halloween Event is an event in October 2017. It began on 23rd October 2017.

About
You can find an NPC named 'The Headless Horseman ', who would appear in a random route on the map occasionally. His arrival would be announced in chat.

The only areas of the map where he will not spawn are: Seafoam Cave, Route 12, and the Pokemon Tower in Lavender Town.

Talking with him will ensure a 100% (for the next Pokemon which can be a Legendary) recolour encounter rate in the same route he stands in '''if he says "Good Luck!" at the end'''. If he doesn't say it, a Hoopa (confined) will be found in the grass.

 Note:  Rejoining the game in the same server will not work.
