On game two or three, go to the maze in the Black Castle. One screen left of the first maze screen will flicker if you carry an object in there meaning one thing, there's ANOTHER object in there. At the bottom center of this room is a closed off cubicle, use the bridge to get in there and you should pick up a ''dot''. Carry this to the screen just above the catacombs (one screen down and to the right of the Gold Castle) and be careful not to lose it as it's the same color as the outside ground. Drop it there and bring two other items onto the screen, run right through the line on the right side of the screen and witness the first ever Easter Egg.

Start playing the game, then push Select on the Atari 2600 console in order to see the game selection screen. Press Down to make your character move over the screen.

If a dead dragon is blocking your way, bring two otheritems you do not need to the same screen. The items on screenwill "flicker", allowing you to pass through them.Alternately, capture the bat and hold him over the dragon's bodyuntil he takes it. Then, just let him go and he will fly awaywith the dragon.
