Where to get it?
Forum-Index → Help → Answered → Where to get it?It has a Special Rarity which means that Pokémon is excluded from being obtained at the Lab or in exchange for Gems from the Gem Collector. The only exception to the Gem Collector are the Kalos Starters (Chespin, Fennekin & Froakie, respectively) from the Kalos Eggs section.
Also, you can get Honey from Rumble Missions which will allow you to lure one to the Honeytree. :)
