Note: If you should warp to this last stage from the training one, the game shall automatically switch to the freed Sam, as only he can fly like the dragon.
Once Sam has reappeared on the screen, you shall have to walk to the right, jump onto a platform to make it move up to the second step of the ground, walk to the right onto the second step of the ground, fly up and drop down on the dragon's head when he flies into view from the right side of the screen (and off the left side of it); you'll then have to land back on the second step of the ground, when the dragon flies back into view from the right side of the screen, and occasionally stops to spit a stream of fireballs at you (there is also a giant Froot Loop in the top-left corner of the room that you will have to collect if you get hit too many times). Once you have dropped down on the dragon's head eight times, he will explode into four pieces (head, wings, tail and legs) - and the German text "GRATULATION! DU HAST DEN DRACHEN BESIEGT!" (meaning: "Congratulation! You have defeated the dragon!") will now appear on the screen as you receive a 15000-point bonus. You can now sit back and enjoy the ending sequence, which is entirely in German:
After the credits have finished the game will go into high-score mode; your score will most likely be the highest since the Commodore Amiga was turned on (or DOSBox was launched through Loonies' DOSShell, for the case of the MS-DOS version), so you should enter your name (up to eight characters) at the top of the table with pride. Once you've done so, the game will return to the menu screen, but it will not close until you select the "EXIT" option on it (however, for the Commodore Amiga version, selecting the "EXIT" option will have no effect, which means that you'll just have to turn the console off).
