Well, he might have all sorts of adventures. He could be sailing to uncharted islands in search of hidden treasures. Maybe he's facing off against rival pirates who also want the Black Pearl. He might even encounter some strange sea creatures along the way.
Perhaps he wins it in a high - stakes card game against a notorious pirate. Jack is known for his cunning, and he might have tricked the other pirate into betting the Black Pearl.
The Never Ending Story 2 has a different cast from what would include Jack Black. Jack Black is typically associated with his own brand of comedic acting in other projects, not this sequel. His acting style and the overall tone of his work don't really match what The Never Ending Story 2 was aiming for in terms of casting.
