Mario's Time Machine (NES)/Door 3

80m B.C.
Now that you're done with the second door it is time to go to the third door. Just like the other times before you have to fight the Koopas. The last Koopa will leave behind the fifth item, a Dinosaur Egg. Pick up the Egg set the machine to 80mBC and travel back to the time when dinosaurs ruled. Go off to the far right until you enter a cave. Select the Egg above and place it there within the cave and a newspaper should appear on the screen with a thank you.

1862
You should find yourself in front of the third door again. Go in the door and fight away the Koopas. The last Koopa will drop a long Stovepipe Hat. Pick up the Hat and travel to 1862 when America was experiencing the Civil War. Walk to the middle of the area where you should see a gate with a sign right above it that says Gettysburg. Put the Stovepipe Hat there and another newspaper should pop up.

Mario will appear outside again covering up the door with bricks.
