Remove all connections from 3ds, add this one.
Go through Mystery Gift as normal.
You can't connect to the internet because you need to go to McDonalds site to give permission, which you need the internet for. Not sure how to get the 3ds working on their wifi.
Had to do this because despite having the toys, Canadian McDonalds doesn't have the event set up.
