This isn't really an idea or a spoiler so I will stick it here.
Club penguin has a new coloring page featuring a penguin on Rockhoppers boat. You can see it here
Now I believe that Club Penguin will make visits to Rockhopper Island possible. Here is why:
1) With the Hot Air Balloon room we see they have perfected travel rooms
2)Coloring pages often relate to current events
3)It has been a legend since Rockhopper first came and last year the made a big legend a reality (ninjas)
4)They promised new rooms this summer and so far... nothing
5)Rockhopper was here once this summer so during his absence he may be readying a Pirate Town
6) The new comic Found Here
