San-Ei Officieel Kirby Pluche met slaapmuts (12cm)

Sleep is one of Kirby's Copy Abilities, first introduced in Kirby's Adventure. In most of its appearances, it is relatively useless, sometimes used as an obstacle. Sleep debuted in Kirby's Adventure, where it is obtainable from Noddy. When Kirby obtains the ability, he falls asleep for a few seconds before waking up, discarding the ability in the process. Sleep also appears in the remake, Kirby: Nightmare in Dream Land, functioning the same way.
