The '''Challenge Node''' is an area found inside [[Bowser's body]] in ''[[Mario & Luigi: Bowser's Inside Story]]'' and its [[Nintendo 3DS|3DS]] remake, ''[[Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey]]''. It is, apparently, located in [[Bowser]]'s spleen. This area is completely optional and does not need to be entered to complete the game.

It is one of the first areas available to Mario and Luigi in Bowser's body after they clear [[Trash Pit]]. The first time Mario and Luigi enter the area, and when a new challenge becomes available, the bros. will be greeted and talked to by an [[Emoglobin]]. In the remake, an Emoglobin will also inform Mario and Luigi if a new challenge is available when visiting [[Toad Square]]. Its icon on the map of Bowser's body looks like an opened [[Nintendo DS]] with two dots of eyes on the top screen and one of mouth in the bottom, which the Emoglobins in the area also resemble.

==Challenges==
Here, [[Mario]] and [[Luigi]] can participate in two challenges and gain items (not included on the page):
*[[Gauntlet]] - Here, the Mario brothers can fight X Bosses, which are optional bosses that are similar to bosses they have fought before, but more tough. One of these bosses, [[Bowser X]], is the toughest boss in the game. In the [[Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey|remake]], giant battles can be re-fought here at a faster-paced difficulty. This is unlocked after defeating [[Durmite]].
*[[Cholesteroad]] - Here, Mario and Luigi use the Special Attacks they have learned to fight the same enemies until the player messes up. This is unlocked after defeating the [[Scutlet (boss)|Scutlet]].

There is also [[99 Block|a block]] that works the same way a [[Rally Block]] does here. If it is hit 99 times in a row, the player can double their [[Coin]]s whenever they want, but once cleared, it cannot be repeated:
