The '''Blue Key''' is a [[key]] found in ''[[Paper Mario: The Thousand-Year Door]]''. It is located inside [[the Great Tree]], in the room after the small [[Jabbi]] army. The key opens the cage where ninety [[Puni]]es (including [[Petuni]], [[Punio]]'s sister) are imprisoned, increasing [[Mario]]'s Puni army from eleven to one-hundred and one.

In the Japanese version when unlocking the blue cage, the game checks for and removes the [[Strange Sack]] from the player's inventory if the player has it (which will permanently prevent it from being obtained again as there is only one in the game). This does not happen in the international versions.

In the [[Paper Mario: The Thousand-Year Door (Nintendo Switch)|remake]], a glitch can be performed when entering the second sublevel for the first time. After the Jabbi holding the Blue Key leaves the room, the player can fire Koops' shell into the entrance to the room with the first hive and retrieve the Blue Key.<ref>https://www.youtube.com/watch?v=CT85neiJnuQ</ref>
