Dooku's frigate was equipped with an escape hatch located in his meditation chamber. The floor opened to a slide shaft leading to the hangar housing Dooku's personal Punworcca 116-class interstellar sloop. The vessel was commanded by a B1 battle droidcaptain and crewed with top-of-the-line models of both the B1 series and B2 superbattle droid series.
Anakin Skywalker infiltrated this ship in his personalDelta-7B starfighter. He had rigged the ship to appear damaged and waited inside the cockpit for the crew of the ship to tow him into the hangar bay. After a short skirmish with the battle droids surrounding him, he was taken into custody after his lightsaber was shot and destroyed by blaster fire.
Obi-Wan Kenobi, wearing a space suit, then infiltrated the ship and located Skywalker in a detention cell. The two Jedi made their way to Dooku's meditation chamber and confronted the Sith Lord. Before they could capture him, Dooku slid though a hidden escape hatch leading to the hangar deck.
