Issues with Regigigas?

Question

Hai
So I've been playing Pearl
I've found regigigas but he won't wake up
I've heard that you have to catch all three regis, but unfortunately I can't seem to locate them and according to the internet, they don't exist in Pearl. If that's true, then why is regigigas even there?
Also, if they ARE in Pearl, where are they?
Thanks!

Answer 1

There was an event a long time ago allowing you to get the other Regis. You'll have to do some Trading or Hacking to get them now, as the event is long passed.
