— Kirby Canvas Curse(pause screen quotation)
Cart Run is a Sub-Game in Kirby: Canvas Curse. Cart Run is derived from the King Dedede boss battle, and only becomes available after successful completion of both levels of the King Dedede boss battle. In the sub game version, three difficulty levels are offered prior to the start of the game. Cart Run is a race against King Dedede in which both will ride in vehicles similar to mine carts. King Dedede's cart rides on a fixed track and Kirby follows a rail generator which is invincible and can destroy star blocks, enemies, and generates track anywhere in the playable area of the course.
This sub-game is simply a matter of crossing the finish lines before King Dedede. Naturally, he cheats and throws hammers at Kirby's cart. Contact with the hammers, Gordo, or any other enemy will result in lost stamina and a slowdown. Kirby can regain lost speed by eating any of the food on screen, eating two at once will provide the Max Speed boost. Smashing through blocks and enemies will accrue more points for Kirby to determine the final score and rank (details below). Although the generator can't be destroyed, the Gordos it comes into contact with remain intact as well. Kirby's stamina needs to be closely monitored as depleted health will end the game.  Several Energy Drinks and Maxim Tomatoes can be picked up to replenish lost health.
A gauge indicating placement in the race between the start and the goal can be seen in the top screen. Level 1 and 2 will be close races, but King Dedede is blazing fast in Level 3.
Scoring and Ranking
Ranks are given upon completion of the Level, or in the case of Level 3, death of Kirby. The ranking system is in a cascading alphabetical format with subnames for each rank given. The higher the score, the lower the alpabet letter will be and thusly the higher the rank. Each Subgame will record the top three scores for each level. Other than for measuring personal progress, and the medal reward for Level 3, the ranking solely exists for bragging rights.
