Sleep is a Copy Ability that first appeared in Kirby's Adventure. It is usually acquired from Noddy. When Kirby receives this ability, he dons a night-cap, blinks his eyes and falls asleep in the very spot he stands, then wakes up in a few seconds. In most Kirby series games, Sleep Kirby appears in the Game Over screen, either waking up, or continuing to sleep depending on whether the player chooses to continue, or quit.
In the debut game, Kirby's Adventure, Kirby did not change appearance when obtaining this ability. He merely fell asleep. Starting with Kirby Super Star, Kirby would obtain a spotted green cap, which he would take off once he woke up again.
Regardless, the green sleeping cap reappears in some later games after the switch to purple was made. In Kirby: Triple Deluxe, the green sleeping cap makes a reappearance in the intro cutscene, when Kirby is sleeping in his house; the model was reused from Kirby Super Star Ultra. Green caps also appear in Kirby Battle Royale as a weapon for putting other fighters to sleep.
As Kirby is immobile during the sleep ability, there are no skills obtained when receiving it in most games.. In Squeak Squad however, if Kirby gets the Ability Scroll for it, it will heal his damage a little bit during his slumber. In Kirby's Return to Dream Land, Kirby may prematurely wake up from sleep if the player shakes the Wii Remote or rapidly pushes the +Control Pad in different directions. This also works in Kirby: Triple Deluxe and Kirby: Planet Robobot, though only by mashing the Circle Pad or +Control Pad. Doing so causes a bubble to grow on his face, which will wake him up when popped. In Kirby Star Allies, shaking the controller or waggling the control stick will wake Kirby up like in past entries, but a Friend can also wake Kirby up by popping the bubble on his face.
There are also Sleep Copy Pedestals that exist in Kirby Super Star, Kirby Super Star Ultra, and Kirby's Return to Dream Land. Some of these appear as a joke ability to restrict the typical choice of two copy abilities before a boss battle (such as in The True Arena). In other cases, they appear as an obstacle in areas with strong winds or currents, forcing Kirby to make difficult maneuvers to try to prevent touching the Copy Pedestals, as touching one will cause Kirby to fall asleep and return to the beginning of the area.
Kirby Battle Royale
Having won the second Copy Ability poll, Sleep was added to the roster of battle abilities, despite many thinking it was a joke inclusion in the poll. As such, this appearance is the first to give Sleep Kirby a proper fighting move-set.
Attacks include hitting opponents with a pillow, blowing huge bubbles, and putting opponents to sleep by placing a cap on their heads. Sleep Kirby wobbles when he moves like he's sleepwalking, and when holding still, will dream of cake, slowly recovering HP in the process.

Super Smash Bros. for Wii U trophy
"You don't get to see sleeping heroes very often. They're so busy rescuing princesses or saving the world, they just don't have time for a little nap. Not so with Kirby! The moment he inhales the snooze-prone enemy Noddy, he pops on his sleeping cap and dozes right off. Ah, Kirby, what dreams might you be having today?"
- Sleep is (and still remains) the only ability that is objectively a hindrance rather than a help (excepting its appearances in Kirby: Squeak Squad and Kirby Battle Royale).
- Despite its non-functionality, Sleep has one Friend Ability associated with it, called 'Friend Wake-Up Call'. When Kirby blows his nose bubble, an ally can pop it early to wake Kirby up.
- Interestingly enough, in Super Smash Bros. for 3DS/Wii U and Super Smash Bros. Ultimate, one of Jigglypuff's alternate costumes has it wearing Kirby's original green Sleep cap. This is likely a reference to its iconic move, Rest, which has a similar effect to the ability the hat references, though with one notable exception...
