Get those Pumpkaboo ready, because we're gonna send out a whole bunch of them through wonder trade on Halloween night! Everyone join in the fun.
Guidelines (You don't have to follow them, but it would be nice if you could):
1. Super size Pumpkaboo are rare, so send out those if you can.
2. Make sure that they only know the move Trick-or-Treat. These little guys are trick-or-treating around game carts, after all!
3. Make them hold rare candies. Halloween is nothing without the treats, and the recipients will surely enjoy it. To get rare candies easily, wonder trade for PokeMiles and exchange them for candy on the Global Link.
4. Give them Halloween themed nicknames.
5. Better natures and IVs are ideal, but not necessary. Some good natures are:
Adamant (Physical Gourgeist)
Brave (Trick Room Physical Gourgeist)
Impish (Physically Defensive Gourgeist)
Relaxed (Physically Defensive Trick Room Gourgeist)
Careful (Specially Defensive Gourgeist)
Sassy (Specially Defensive Trick Room Gourgeist)
6. Enjoy it. This is supposed to be fun, not a chore.
Alternatively, You can send out Pumpkaboo holding everstones named "I Got A Rock"
Everstones can be harvested from Roggenrola via thief.
Dont have a Pumpkin to send? Dont be afraid to ask, or send any kind of Pokemon you think would fit into the Halloween theme!
