How to receive Gekkouga

Receive the Gekkouga from your seat, either before the movie begins or after it has ended

Important: Make sure to receive the Gekkouga during the intermission right before or after the movie screening, while sitting in your audience seat. Also, make sure to keep your Nintendo 3DS series game system closed so no light from the screen can be seen while the movie is being screened in order to not bother other members of the audience.

Advance preparation: Go to the theater fully prepared to receive the "Gekkouga"!
Bring the following:
*A fully charged Nintendo 3DS-series system
*A copy of either of the Nintendo 3DS games "Pocket Monsters X/Y/Omega Ruby/Alpha Sapphire"
(both the cart version and the download version can be used)

Make preparations in the game itself as well:
*Make sure you won't have the max amount of wonder cards.
*Make sure the delivery person isn't already holding a gift.
*Make sure the wireless communication on your Nintendo 3DS system is turned "ON"

Step 1: Receive the "Wonder Card" in the theater
Turn on the Nintendo 3DS series system after making the game accessible, then start the game, choose "Mystery Gift" from the menu screen, and receive the "Wonder Card" by following these steps:
*After starting the game, choose "Mystery Gift" from the title menu and press A.
*Select "Receive Mystery Gift" and press A.
*On the next screen, select "Receive via local communication" and press A. Then select "Yes" to confirm you want the communication to start and press A.
*Confirm the gift, then select "Yes" and press A to finally receive it.
*Select "Yes" and press A.
*You will see a confirmations screen once the gift has been received. At this point, the gift has automatically been saved, so you can safely turn the power off.

This is all you need to do in the theater itself!

Step 2: Receive the "Gekkouga" from the Pokémon Center in the game!
Once you have received the "Wonder Card", you can receive the "Gekkouga" from the Pokémon Center. Choose "Continue Play" from the menu screen to resume your game, then follow these steps to receive it:
*After resuming the game, ensure there is an "empty" space among your Pokémon on hand.
*Go to a nearby Pokémon Center (it doesn't matter which city it is).
*Talk to the delivery person in blue clothes with the A button to receive Gekkouga.
*The Gekkouga will now appear in the "empty" space among your Pokémon.
*After checking your Gekkouga, make sure to save your progress by using the "Save" function.

Please note:
*Pokémon Centers are located in various spots throughout the game. It is estimated you will have to play for about an hour until you can first visit one (individual differences apply).
*If you have received a different "Wonder Card" before, please talk to the delivery person in blue clothes and receive that previous gift.

*When you first start playing "Pocket Monsters X/Y/Omega Ruby/Alpha Sapphire", the "Mystery Gift" menu will not be avilable. Those of you playing for the first time will see a different title menu instead. Choose a language from here and start the game, then play until the "Save" function becomes available to you and save the game. Next, press the HOME button on your Nintendo 3DS series system and end the game, then restart it and the standard title menu will display.

If you are unable to receive the Gekkouga, please check the following steps:

Step 1: If you are unable to receive the "Wonder Card"
If the game tells you you have too many Wonder Cards:
The game will tell you this if you have 24 "Wonder Cards" and have received at least one gift from the delivery person (meaning there is a "Wonder Card" that can be discarded). If you choose "Yes" here, you can then throw away "Wonder Cards"
*You can not throw away "Wonder Cards" for gifts you haven't received.
*Once you have thrown away "Wonder Cards", press the B button and select "Quit", and the card album will automatically be saved and you will be returned to the "Mystery Gift" menu screen.

If the game tells you you have too many gifts:
The game will tell you this if you have 24 "Wonder Cards" and haven't received any gifts from the delivery person. Resume your adventure and head to a Pokémon Center to receive a gift from the delivery person. Next, throw away a "Wonder Card" as detailed above.
If the game tells you wireless communication is turned off:
If you have a New Nintendo 3DS/New 3DSLL/2DS, go to the "HOME menu settings" menu in the top left corner of the home menu, then to "Wireless Communication/NFC" from there, and activate it. If you have a Nintendo 3DS/3DSLL, set wireless communication to ON by sliding the wireless switch at the right hand side of the system marked WIRELESS.

Step 2: If you are unable to receive the Pokémon
If the delivery person tells you you have too many Pokémon on hand:
You will see this message if you talk to the delivery person when having 6 Pokémon on hand. In order to receive a giveaway Pokémon, ensure there is an "empty" space among your Pokémon on hand. Use the computer in the middle right side of the Pokémon Center to put one of your Pokémon on hand in one of the boxes in the computer. Then talk to the delivery person again, and you will be able to receive the Pokémon.
