In Pokemon Black for the DS, there is a machine on the second floor of the Name-Rater Service Building in Castelia City called the Relocator, which you have to use for some events, and to get the Lock Capsule to get TM95 Black Out.
The machine requires a password. You’ll recognize the password if you unlocked the Mystery Gift in previous version though. The password is: Everyone Happy Simple Connection
I’m not sure what it means, but it sure is great engrish!
