Cholesteroad

The Cholesteroad is an event in Challenge Node from Mario & Luigi: Bowser's Inside Story and its remake Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey. The name is a pun on both 'cholesterol' and 'road'. Here, the player partakes in using Mario and Luigi's Bros. Attacks in a manner that progressively become more difficult to use until the player makes a mistake. The Cholesteroad features two categories, Endless Mode and Juuuuump Mode.

The Cholesteroad is Mario and Luigi's counterpart to Bowser's sessions with Broque Madame, where the player's agility with Bowser's Brawl Attacks is tested.

Endless Mode
If the player chooses Endless Mode, the player can use five of the Bros. Attacks which slowly increase in complexity and speed, against an endless swarm of Cholesterons; the player is scored based on how long they can keep up the progressive difficulty before failing once. In this mode, the player can do all the Bros. Attacks except for the Fire Flower, Mighty Meteor, Snack Basket and Falling Star.

Juuuuump Mode
In Juuuuump Mode, the players use the Jump Helmet to move as far a distance as possible within a limited time frame, which can be replenished by grabbing the extra time clocks. Points are allotted based on the distance traveled before making a mistake or running out of time. 25 and 50 points are required to obtain the B Rank and A Rank, respectively in the Japanese version of the original game, while the European and American versions of the original game require 30 and 60 points for the B and A ranks, respectively.

Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey
Note: if the Gold Rank is achieved without ever stopping after Bronze and Silver ranks, the coin prize from each rank will be added up together.

Trivia

 * Unlike The Gauntlet, which is unlocked after beating Durmite, the first boss remade into an X boss, the Cholesteroad is not unlocked after getting the Green Shell. Instead, the player must first beat the Scutlet boss.
