The Migrator is a pirate ship that sees service under Rockhopper and Yarr. The ship's design is like a small Galleon clipper ship. It is used often for Rockhopper and Yarr's adventures on the seven seas and is considered Rockhopper's home.
The ship is supposedly built from wood as, according to Rockhopper, it was assembled on Club Penguin Island. It is a streamlined ship with two floors, high-rise sails, and multiple portholes. Rockhopper has used the ship in many expeditions for which he has documented in his journal.

Island Adventure Party: Rockhopper's Quest
For the Island Adventure Party: Rockhopper's Quest, Rockhopper wanted to allow penguins to venture on the ship for a quest to construct a new beacon for Shipwreck Island. To make travel times faster, he asked Gary to upgrade the ship.
Gary retrofitted temporary upgrades to The Migrator to make its speed significantly fast and to endure more damage. The upgrade included a titanium hull and two giant jackhammers added to the front of the ship for protection from icebergs, plus a giant fan to provide reliable wind for the sail.
- The ship contains two flags. The flags on the ship resemble the Jolly Roger flag but with a puffle instead of a skull.
- The ship's name originated from when Aunt Arctic asked Rockhopper where he was migrating to.
