Jackson and Tuliano return to the pirate world through the hole in Jackson's room. They find themselves on a different ship, with a different crew. They are captured by the Black Pirates, a rival gang of the Happy Pirates. They are led by Captain Black, a ruthless and greedy pirate who wants to find Zurina and claim the treasure for himself. He has heard rumors that the Happy Pirates have found the island, but he doesn't know that they have been trapped there. He plans to use Jackson and Tuliano as bait to lure them out and capture them.
Jackson and Tuliano try to escape from the Black Pirates, but they are outnumbered and outmatched. They are taken to Captain Black's cabin, where they are interrogated and tortured. They refuse to reveal anything about Zurina or the Happy Pirates. They hope that their friends will come and rescue them.
Meanwhile, on Zurina, the Happy Pirates are still alive. They have survived the collapse of the chamber and found another secret passage that leads to a hidden cave. They have discovered that the treasure is not gold or jewels, but something more valuable and powerful. Something that can change the world. Something that can open holes.
They have discovered a portal machine.
The portal machine is an ancient device that can create holes in space and time. It can transport anyone or anything to anywhere or anytime. It can connect different worlds and different realities. It is the ultimate treasure.
The Happy Pirates have learned how to use the portal machine and have explored different places and times. They have seen wonders and horrors, beauty and ugliness, joy and sorrow. They have learned a lot and had a lot of fun.
But they have not forgotten.
They have not forgotten their friend and their chef.
They have not forgotten Jackson and Tuliano.
They have not forgotten their mission and their friendship.
They have not forgotten their home.
And they have a plan.
A plan to go back.
A plan to save them.
A plan to finish what they started.
A plan that involves the portal machine.
The portal machine that opens up in Captain Black's cabin one day.
The portal machine that starts a new adventure.
