Extra Stage

Extra Stages are stages that are exclusive to Challenge Mode which can be accessed by completing a difficulty level under a certain condition. They serve as an extension to the difficulty levels, which will be rewarded to the player if they play well enough.
== Appearances and Requirements ==
In Monkey Ball and Super Monkey Ball, the requirement for reaching the Beginner and Advanced Extra floors is to not lose a single life. To reach the Expert Extra floors however, the player mustn't use a continue instead. Additionally, to reach the Master floors, the player also mustn't use a continue in the Expert Extra levels.
In Super Monkey Ball Jr., Super Monkey Ball 2 and Super Monkey Ball Deluxe, the requirement is to not lose a continue, which is the same across all difficulty levels.
The Extra Stages would later return in Super Monkey Ball Banana Mania, where the player can access them by clearing a difficulty level without the use of the Helper Function.

== Trivia ==
*Super Monkey Ball Deluxe has the largest number of Extra stages in the series with a total of 70, while Super Monkey Ball Jr. has the smallest number with a total of 9.
*There was a false rumor where, on the Japanese version of (Super) Monkey Ball, the Beginner and Advanced Extra floors were also unlocked by not losing a continue, as opposed to not losing a single life. This is not true, as the requirements are the same across all versions of these games.
