From the Super Mario Wiki
Rolling Panic is a minigame from DK: Jungle Climber. Accessible from the Challenge menu, this minigame is very simple to play. The player must jump over the logs rolling down the hill and avoid the boulders. When the player gets a determined score in a pre-determined time, they win. This minigame, like the other five in this mode, has three "levels" unlockables beating the first to take the second, and go on.
Level one finishes when the player got 100 points, level two with 150 points, level three with 250, and the next level is "infinite": When the player gets hit by a log or boulder, they lose.
An Adobe Flash version of this minigame was playable on the official DK: Jungle Climber website. The browser version was largely the same as the original minigame, although it did not have a goal score to surpass.
