Guard Door
Guard Doors are huge stone faces of Bowser that act as gates in Paper Mario. In three areas of Bowser's Castle a Guard Door can be found, they'll need to have something be done before they let Mario pass. If Mario completes the objective the gate will split in half and open.
The first one Mario comes into contact with will open a trap door, sending Mario to a jail cell, after Mario escapes the gate lets him in. The second will quiz Mario five times on various enemies, however, if Mario's wrong three times he'll have to fight three Anti Guys. The third and final is a battle with the Super Ultra Mighty Koopa Bros. the Great, who get knocked away by the improved Jr. Troopa, whom Mario will have to fight. The third Guard Door is the exit from Bowser's Castle, leading to Peach's Castle.
Trivia
- When the 3rd Guard Door at the end of the castle encounters Mario, he claims he has much better defense than the other Guard Door's. It should be noted that if Mario answered 3 question's wrong during the encounter with the 2nd Guard Door, he would make Mario face 3 Anti Guy's, and it seems highly unlikely that the Koopa Bros. would be stronger (the Koopa Bros weren't fought because of Jr. Troopa.
