The migrator always stays with Rockhopper, whether he is on Rockhopper island or on the club penguin island. Currently (April 2013), the migrator is with Rockhopper on Rockhopper island, but when he'll come to club penguin, he'll be sailing on his migrator.

Rockhoper is only seen when his ship has come to Club Penguin at the beach. See the related links below for the Rockhopper Tracker 2010 and some tips on how to find Rockhopper.
Usually every 6 months.
wait for him to come :[ it maybe hard
captain rockhopper already came in 2009, he will come in 2010
how am i going to know. im asking for this question! from:penguin6524. P.S. that's my club penguin penguin name.
It depends whenever the developers decide for Rockhopper to come to the island. I have met Rockhopper twice and if you want to see go onto Club Penguin, Big Surf (if full southern lights) and find Ocean Comet and look at the background.
Rockhopper comes to Club Penguin about every 4-6 months. He came in March 2009, then in fall of '09.
Rockhopper's ship sunk and then he tried to go to outer space and a flying monkey ate him.
His name is Rockhopper and he normally comes about once a month or so.
Actually, Rockhopper doesn't really come from Rockhopper island. Its just an imaginative story created by club penguin. Club penguin always plans how far Rockhopper's ship is, what he will face and in the end, when he will reach, and makes stories out of them. Sorry if this answer became a spoiler for you.
