And this is what he looks like on Club Penguin as a penguin:

How to Find Rockhopper
The first thing you oughta know is whether he is online or not. You can do this by going onto the Club Penguin home page and seeing if his ship is there. Usually it is there, because he is on most of the time.
Second, remember that you can’t trust Rockhopper Trackers. Those are manually updated, so it will most likely not be accurate. To find the server he is on, try searching servers that are not normally busy, but are busy at the moment. That is a sign that he is on that server
There are some rooms you should check first: The Migrator, the Ship Hold, Captain’s Quarters, Pizza Parlor, Dock, Beach, and the Iceberg.
Look for people yelling stuff about Rockhopper. Try to get a group of friends together to look for him. Rockhopper usually is on a server for about 15 minutes, sometimes 20. If you see lots of people dressed like pirates, then he is probably somewhere near.
When you find him, you can receive a gift from him (you can’t be his buddy). You click the button that would normally be the add as buddy button. Sometimes he will address you or your question directly!
Use all this to help you find Rockhopper!
