Try to finish with as many Life Pieces as you can—collect a lot and you'll unlock rewards!”
|— Devilish Mode • Kirby's Extra Epic Yarn|
Before entering a stage, the player has the option to pick Normal Mode or Devilish Mode. Upon picking Devilish Mode, the stage will start up as normal, but after a short period of time (or upon reaching a certain checkpoint), a Devil will rip through the fabric and appear; this is noted by a change in the music playing, becoming a short, alarming tune. Depending on the stage, one of three Devils will appear, and each of them have different tactics. The Me-Devil flies near the top of the screen and moves back and forth; after a period of time, he grabs a button, then puts spikes on it before dropping it straight down. The Ye-Devil has a drill on his head and flies near the right or left sides of the screen, moving up and down; after aligning himself with Kirby's position, he will start oscillating before a shine appears on his drill, after which he will dash forward at high speed. The We-Devil floats around, pointing its tail at Kirby's position; after the tail aligns with Kirby's position, the We-Devil will flap its wings and then shoot a flashy arrow from its tail.
Aside from the Devils, Kirby also has a limited amount of health, having five Life Pieces. Taking damage from any source results in the loss of a Life Piece; some forms of damage can result in Kirby losing multiple pieces. However, Prince Fluff appears roughly halfway through each stage, and holds a Life Bead over his head; grabbing this Life Bead grants Kirby 100 Beads and restores any lost Life Pieces. After Kirby reaches the end of the stage and rings the Bonus Wheel Bell, any Life Pieces he has will be recorded for the stage and added to the Collected Life Pieces chart, where the player obtains a piece of furniture for obtaining five Life Pieces collected; this only counts towards Kirby's best record for Life Pieces, meaning the player needs to beat each stage with 5 Life Pieces to get all of the furniture. If Kirby loses all of his Life Pieces in a stage, he will have to restart the stage from the beginning.
