Pokémon caught at the Honeytree have a higher chance of being Shiny and Mega-Able' with shiny pokemon having their own artwork.
HoneycombsHoney may be produced.
When you enter the Honeycombs, you are given the option to leave a Male Combee there. If you leave a Combee at the Honeycombs, it will eventually produce Honey which can be claimed every once in awhile.
There is also the possibility of building more Honeycombs, to get space for more Combee. The Max. Number of Honeycombs you can have is 3.
MooMoo RanchMooMoo Milk is produced.
MooMoo Milk is obtained through 'milking' the Miltank left there, through the item Milker, which can be obtained at the item shop for 2000 Pokedollar. Also, the Miltank can be 'milked' more than once.
For a Miltank to produce MooMoo Milk, you have to leave enough berries at the ranch. They will happily accept any berry.
