Many animated characters have surprisingly noisy eyes. One can't blink in a cartoon without making all variety of noises.
Most likely, these evolved from depictions of blinking in non-moving Sequential Art. Rather than devoting whole panels to a character moving their eyelids up and down, the artist would apply an onomatopoeia or an Unsound Effect to get across the point that the character is blinking. Manga tended to use "piku", while western comics used "blink blink".
Somehow these "sounds" carried over into animation. Anime characters make sounds like "poit" or something vaguely reminiscent of "piku". Western cartoon characters make a "plunk" or "plink" sound.
These sound effects are usually reserved for intentional blinking, the blinking that indicates confusion or incomprehension. Frequent, involuntary blinking (like the kind you're doing right now) is left silent, because it would be very distracting otherwise. Unless, of course, said involuntary blinking is a twitch.
- Arika in Mai-Otome does this a lot.
- The girls in Azumanga Daioh sometimes have audible blinks.
- Damn near every blink in This Ugly Yet Beautiful World has an audible ploit sound.
- Happens regularly to the girls in Petite Princess Yucie, especially Yucie.
- Sailor Moon: Usagi's eyes make "plink" sounds when she transforms in Sailor Moon. Also, one-episode occasions of eye-noise happens.
- Emporio Ivankov in One Piece has an attack called "Death Wink" ("Hell Wink" for the improved version) which is Exactly What It Says on the Tin; blinking so hard it produces a shockwave.
- Happens in an episode the English dub of Cardcaptor Sakura after Tomoyo (Madison in the dub) brings Sakura back to attention.
- Urusei Yatsura. Lum and Ataru do this at least once. Lum does it when she and Ataru are trapped inside a container and are about to kiss. Ataru does it after the container falls apart and reveals that they're surrounded.
- In Jeff Smith's Bone, the sound of Fone Bone rubbing his eyes is written out as "squinky squinky".
- Pretty Guardian Sailor Moon does this occasionally, which comes off as rather weird and disconcerting.
- The episode "200" from Stargate SG-1, during a Star Trek: The Original Series parody. Colonel Carter, as a thin analog of Lt. Uhura, has squeaky blinking syndrome.
- Doctor Who : It's incredible how loud the Doctor and Donna's eyes are when they're reunited. Granted, there's a door, a room, and a window between them, so they have to have SOME way to communicate, but STILL...
- In The Lost Mind of Dr. Brain, sometimes Rathbone gets disintegrated except for his eyes, which then blink without eyelids.
- Piston Honda has squeaky eyebrows as an audio cue for one of his attacks.
- The Wii remake gives Mr. Sandman a distinct squeak when he winks before throwing one of his powerful, lightning-fast uppercuts. This is your cue to punch him in the face before he does the same to you. It's also an Internal Homage to the first Punch Out, where Mike Tyson would wink before throwing out fast straight punches, which did not give an audio cue, only a visual one.
- Whenever a character blinks in the BIONICLE Flash-videos, their optics make mechanical sounds akin to camera noises.
- Expect this when a Hello, Nurse! starts batting her eyelashes at anyone. Though it tends to sound more clicky than squeaky in that instance.
- Zorak on Space Ghost Coast to Coast, Cartoon Planet, and The Brak Show would sometimes make an audible "plunk" noise when he blinked.
Zorak: First, you have to be funky-fresh.
- One skit on Cartoon Planet had Space Ghost making fun of this: "Loud-eyes!"
- In another skit, Space Ghost tries to get Zorak to teach him to make the same noise. All he could manage was a comical squeak. Zorak explains what his problem is:
Space Ghost: I'm funky! I'm fresh!
Zorak: Next, you have to have eyelashes.
Space Ghost: Oh.
- Which makes no sense when you think about it, but that's probably part of the joke.
- Space Ghost actually does replicate it in a episode of Coast to Coast, causing Zorak to retort, "Hey! That's my sound effect! I'm suing!"
- At one point Zorak blinks in rapid succession for a few seconds.''plunkplunkplunkplunkplunkplunkplunkplunk..."
- This could be an homage to Looney Tunes. Often when a character blinked in those, there would be a xylophone or a violin pluck sound effect accompanying it.
- On The Simpsons when forced to wear uniforms the school children lose all personality and even begin to blink in unison, creating a pronounced "squish". Skinner responds "I love that sound".
- Also happened in one Drawn Together episode (that one with the sit-in). Especially
Spongebob SquarepantsWooldoor Sockbat.
- XR from Buzz Lightyear of Star Command makes a vaguely mechanical noise when he blinks; this may be justified by the fact that due to being a robot nearly everything he does results in a mechanical noise.
- Among its many Mickey Mousing techniques, The Fairly OddParents! makes active use of noisy, often simultaneous blinking to illustrate confusion.
- Avatar: The Last Airbender, especially Momo.
- Orko from He-Man and the Masters of the Universe (1983) sometimes makes very odd noises when he blinks.
- Dexter's Laboratory and The Powerpuff Girls both use plinks for eye blinks and violin chords or swishes for eye movements, as part of a whole repertory of stock in-house cartoon sounds. Probably used on lots of other Hanna-Barbera and Cartoon Network Productions shows as well.
- My Little Pony: Friendship Is Magic is very similar to the above in this regard.
- Characters in SpongeBob SquarePants make audible blinking noises at times during Beats. The most common sound is shared with Squidward's footsteps.
- Sid and Sue of Three Delivery tend to blink audibly when Tobey says or does something dopey or bizarre.
- Henry and June on KaBlam!! Same with Sniz, Fondue, and the Off-Beats.
- The eponymous mouse of the German Die Sendung mit der Maus note has very audible eyes, to the point where they've become a trademark. (It sounds more like "clack-clack" and is done with castanets.)
- Horrible Histories does this in every blink.
- Used a lot in early incarnations of Scooby-Doo, usually followed by a "boing!"-accompanied Double Take.
- Transformers Animated had the Cybertronians do this. Justified, since theyre robots.
- Fluid can squirt between folds of the eyelid and produce a sound if they are closed fast and forcibly enough. No-one but you will hear it, though. And you're probably trying right now.
