[[RidiculouslyCuteCritter Winks]] are happy little creatures who bring good dreams to humanity. Their job is also to stop the [=HoodWinks=], their {{Evil Counterpart}}s who bring people nightmares. And for the most part, this cycle of giving dreams and stopping nightmares goes smoothly... until Nitekap, a [[BuffySpeak mad scientist/sorcerer-type guy]] with raging insomnia, decides that if ''he'' can't sleep well at night, well, ''no one'' will. He and his sidekick [[BearsAreBadNews Threadbear]] kidnap all of the Winks until there are only 40 left, and even those he manages to snatch up.

Enter Ruff and Tumble, a pair of [[BrotherSisterTeam siblings]] who have taken it upon themselves to rescue the Winks from Nitekap and Threadbear. Fearlessly, they enter the [[DreamLand world of dreams]] to hunt out the missing Winks. Armed with only a candle and a teddy bear (and the ability to transform into a number of more powerful forms), the two siblings set out to stop the evil Nitekap and ensure the world's good dreams continue for all eternity!

This PlatformGame was released in November of 1999 exclusively for the original UsefulNotes/PlayStation. A UsefulNotes/Nintendo64 version of the game was planned, advertised, and completed, but due to financial troubles, it was never released and its existence was considered an UrbanLegendOfZelda... until 19 years later, when a UsefulNotes/{{Kickstarter}} [[https://www.kickstarter.com/projects/retrogames/40-winks-a-new-nintendo-64-game campaign]] was created by Piko Interactive to finally give the Nintendo 64 version a proper release on the system, making it the first game to be published on the Nintendo 64 since its discontinuation.

!This game contains examples of:
* ActionGirl: Tumble, especially in her Ninja and Superhero costumes.
* BearsAreBadNews: Zig-zagged with Threadbear. On one hand, he's a threatening-enough boss, and TheDragon to Nitekap. On the other hand, he's so beleagured, he almost falls into MinionWithAnFInEvil status.
* BigBad: Nitekap.
** TheDragon: Threadbear.
* BigBoosHaunt: Haunted Hijinks in it's entirety.
* BrotherSisterTeam: Ruff and Tumble, respectively.
* BubblegloopSwamp: Drip Drop Swamp, in Ancient Adventures.
* ChildMage: The Magician transformation.
* DamageSpongeBoss; The final boss, ironically moreso than all previous bosses. There isn't much challenge in beating him; the real problem comes with having the patience of eradicating all of his ''16'' lives.
* DistaffCounterpart: Ruff and Tumble to each other; the only difference being their hair color, hair style and color of their pajamas.
* DownTheDrain: Pirate's Ahoy, complete with many of the trappings appropriate to it.
* DreamLand
* EternalEngine: Some of the space levels are a bit like this.
* EverythingsBetterWithSpinning: The Ninja costume has a spinning attack you can use while running. Keep pressing the button, and you'll keep spinning--but do it too long, and your character gets dizzy!
* [[EvilBrit Evil Brits]]: Nitekap and Threadbear.
* EvilCounterpart: The [=HoodWinks=] to the Winks.
* ExplodingBarrels: Appears once in Haunted Hijinks, some parts of Astral Antics, and in abundance in Pirate's Ahoy.
* ExpositionFairy: Wakey Wakey the alarm clock. In early levels, you can touch icons of his face for advice, but in later ones, he just describes the levels to you.
* FloatingLimbs: Both the Winks and the Hoodwinks have feet but no limbs. Wakey-Wakey also has hands and feet but no arms or legs.
* GangplankGalleon: There's a whole pirate-themed world!
* GoombaStomp: It's doable, if not always feasible.
* GottaCatchEmAll: The titular 40 Winks, of course, but also the 12 [=DreamKeys=] in every world, necessary to face the boss.
** Within the levels, you've also got to typically find all 40 cogs to complete it.
* HeelFaceTurn: [[spoiler: Nitekap just needed a good night's sleep is all.]]
* HubLevel: The house is the main hub, but each of the individual worlds also has its own hub from which you access the sub-levels and enter the world's race.
* IdleAnimation: They will usually yawn and stretch in place.
* ItsAWonderfulFailure: There are three GameOver cutscenes where the game taunts you for your failure.
* [[KidHero Kid Heroes]]: Ruff and Tumble.
* LethalLavaLand: Goes hand-in-hand with {{Prehistoria}}, as it often does.
* LittleMissBadass: Tumble, especially in her transformations.
* LittleProfessorDialogue: Tumble in the opening cutscene, on the origin of dreams.
* LostWoods: Witch Way Woods, as part of Haunted Hijinks.
* MakeMeWannaShout: Your basic ranged attack, when not transformed, is a scream attack.
* MiniMook: Hoodwinks.
* {{Ninja}}: The Ninja costume, of course.
* OxygenatedUnderwaterBubbles: There are underwater vents that spew breathable bubbles. Just running through them is not enough, however; you have to linger on them to get a full-sized gulp of air.
* PaddedSumoGameplay: Even the {{Mooks}} in the very first levels of the game have ridiculous amounts of health! You yourself have 50 "Zzzs," but they drop away fast.
* PaletteSwap: Most enemy types have two or three different color variants. They're pretty much the same in terms of damage and health, they just provide some variety.
* PinkGirlBlueBoy: Tumble wears a pink nightshirt, while Ruff's is blue.
* {{Prehistoria}}: The prehistoric level, Ancient Adventures, of course. However, its individual levels hop around a bit in theme.
* PunnyName: Threadbear is a pun on both his status as a teddy bear, and on "threadbare," or worn-down. There's also [[WhoNamesTheirKidDude Ruff and Tumble...]]
* PurelyAestheticGender: You can choose between playing as Ruff (male) or Tumble (female), but they're identical. In the N64 version, however, a second player could control the one you didn't.
* RacingMiniGame: Each world has one, against Threadbear's Champion in that area. The N64 version would've had/does have (depending on your opinion on things) multiplayer racing.
* RidiculouslyCuteCritter: Aww, wookit the cute widdle Winks!
* RuinsForRuinsSake: Tippy Toe Temple.
* ScreamsLikeALittleGirl: Ruff's scream attack is actually much more high-pitched and louder than Tumble's.
* SimpleStaff: Tumble's Ninja costume uses one.
* SpaceZone: Astral Antics.
* SpeakingSimlish: Most enemies, otherwise this trope is averted.
* [[spoiler: TheUnfought: Nitekap.]]
* VomitIndiscretionShot: The caveman form's special attack, which pukes bones all over your enemies.
* WhoNamesTheirKidDude: "Ruff" and "Tumble"?
