While in the museum, the player can enter a cheat code to receive a golden pickaxe from Tower of Druaga. Inside the room for Tower of Druaga is a wall that can be broken with the axe. Behind the wall is a special fight scene between Gilgamesh and the final boss Druaga.

Towards the end of the fight, the player can press X on the Blue and Red Crystal rod to help Gilgamesh defeat Druaga.

Besides this scene, there is a special version of the Tower of Druaga game floating towards the right. Several aspects of this version of the game have been altered.
