Opening your gates:
- Talk to Orville and click on " I want visitors"
- Then "Online play" if trading online.
- When trading with strangers, click "Invite via Dodo Code"
- Then "The more the merrier".
- Then "Yeah, invite anyone".
- A dodo code will be created. I suggest that you PM the user that you will be trading with.
- If you forgot the dodo code just talk to Orville and select "I forgot the Dodo Code".
After the trade is over, click on "Please close the gate".
Visiting someone:
- Talk to Orville and click on "I want to fly!"
- Then "I want to visit someone".
- Then "Online play".
- Then "Roger".
- If a dodo code from a stranger was given to you, click on "Search via Dodo Code".
- Orville will ask you to enter the Dodo code.
- The rest I'm saying off memory; but I think that he will mention the name of the island that you'll be visiting.
- Then he'll ask if you're ready to travel.
If there's no hiccups like the other user had their inventory open, were using the nookphone, or talking to a villager, then everything will go smoothly.
Once the trade is over, talk to Orville and hit the I want to leave option.
