Truck Monsters are enemies in Kirby's Epic Yarn. They are cars who have the same form, but depending on the driver, have different colors. Truck Monsters have yellow and red button headlights (even though they look more like eyes), black wheels and a gray spike on their rear end. Truck Monsters being driven by Waddle Dees are green. Truck Monsters driven by Dandans are orange, and Truck Monsters being driven by Cyclods are blue. Truck Monsters appear in three levels in the game, each which feature the Off-Roader form. These levels include Pyramid Sands of Hot Land, Dusk Dunes also of Hot Land, and Frigid Fjords of Snow Land. Truck Monsters do not attack, but instead race to see who can get to the finish line first. Kirby and Prince Fluff in Off-Roader form can easily damage these enemies by jumping on them, however, if they bump into the spike on the enemy's rear end, they will spin out and lose Beads. If the player is boosted by the booster Metamortex, which shows up whenever the player is in Off-Roader form, they can ram into Truck Monsters without being damaged, causing that Truck Monster to lose control instead. The only Off-Roader section where Truck Monsters are absent is in Meta Melon Isle of Dream Land.
