From WiKirby, your independent source of Kirby knowledge.
Noddy is a sleepy creature with no arms and a night cap who appears frequently in the Kirby series. In every game it appears in, Noddy is well known for inducing the Sleep ability when swallowed by Kirby. It, unlike many other enemies, does not try to attack Kirby, but can hurt him if he walks into Noddy, or if Noddy accidentally walks into him.
Appearance and behavior
Noddy resembles Kirby but has yellow feet, no arms, a slightly different color and wears a different color night cap, usually orange and yellow. Noddy's eyes are also more round and spread out on its face than Kirby's and has an off-white cheek blush as opposed to Kirby's rosy pink or magenta.
Noddy is not inclined to move very much. It prefers not to walk off of ledges and will not try to jump. As expected, Noddy spends most of its time asleep, making it very easy to avoid. Noddy is capable of jumping if possessed by Ghost Kirby, but interestingly enough, it assumes its 'sleeping' pose while jumping.
Kirby's Adventure/Kirby: Nightmare in Dream Land
Noddy made its debut appearance in this game, and appeared again in the remake. Here is where its look and characteristics were established. Noddy was capable of appearing in many colors here, including green.
Noddys are very uncommon enemies generally, though they appear in large numbers in Rainbow Resort. Noddy can be found in the following levels and stages:
Kirby Super Star/Kirby Super Star Ultra
Noddy reappears in these games, and can be found in every main game except for Spring Breeze and Gourmet Race. In Milky Way Wishes, Noddy is one of the few enemies that can provide an ability when swallowed, and swallowing two at once allows Kirby to get a Mix, bypassing the Copy Essence Deluxe requirements for that mode.
Noddy can be found in the following places in Kirby Super Star and Kirby Super Star Ultra:
Kirby Air Ride
Noddy appears in this game, and can usually be found sleeping on courses in Air Ride mode.
Kirby & The Amazing Mirror & Kirby: Squeak Squad
Noddy returns in these games, appearing and functioning exactly as it did in Kirby: Nightmare in Dream Land.
In Kirby & The Amazing Mirror, Noddy can be found in every major area of the Mirror World except for Moonlight Mansion, Cabbage Cavern, and Olive Ocean.
In Kirby: Squeak Squad, Noddy can be found in the following levels and stages:
Kirby's Return to Dream Land, Kirby: Triple Deluxe, Kirby: Planet Robobot, & Kirby Star Allies
In-game capture of Noddy from Kirby's Return to Dream Land
Noddy appears in each of these games, acting much like it has before and sharing a more-or-less unchanged look throughout. Given its status as an enemy that provides a limited-use ability, it does not see much time in the spotlight unlike its more permanent-ability comrades.
In the anime
In the episode, "The Pillow Case," King Dedede receives a gift from N.M.E. for being a loyal customer. This gift happened to be pillows that make whoever sleep on them have nightmares about Kirby, and, eventually, make them want to get rid of him. Later in the episode, they find out that the reason the pillows do this is because there are Noddies inside them. Noddies here have a different color scheme to those in the games, having a yellow body and pink hat.
