Some videos have characters having inexplicable (if not outright nonsensical) side effects from some injuries they get, such as needing an oxygen mask (or being unable to speak) for a year when they only broke their leg, or lifetime oxygen tanks and paralysis from a stink bomb. Even if you needed an oxygen mask from breaking your leg or taking in the scent of a prank-strength consumer stink bomb, you probably wouldn't need one for that long.
"X Pours Rat Poison on the School Lunch" videos involve the troublemaker tampering with the school lunch by pouring rat poison onto the food, which is then unknowingly served to the students. Upon consumption of the tampered foods, the students merely experience stomach pain and throw up. In reality, rat poisoning tends to have far more horrific effects on humans. Some of the symptoms can include spontaneous and/or internal bleeding, muscle spasms, seizures, dehydration, cerebral edema and an altered mental state. In large doses, it could even prove fatal.
Specific examples:
Caillou Fakes Sick (original video deleted, video part of compilation) has Caillou faking sick by showing his mother that his temperature is 103°Fnote for those outside the United States, that's 39°C, and a reasonable reading for a high fever, which ranges between 39 and 39.9°C after holding it in hot water. Later, his mom takes his temperature again and discovers Caillou's actual temperature is...70 degreesnote 21°C. That's actually a dangerously low temperature for anyone's body to be at (Hypothermia starts below 95°Fnote 35°C), and yet Caillou is shown perfectly healthy.
Even worse in another "Caillou Fakes Sick" video, Caillou Fakes Sick Gets Grounded, where this time, the thermometer is 3. Whether it's Celsius or Fahrenheit, that is certainly fatal.
In Caillou hurts Rosie/Grounded, the nurse is able to instantly fix the newborn Rosie's injuries after a pissed off Caillou throws Rosie against the ceiling. Babies, newborn or not, are very fragile, so Rosie likely would have been killed had she been thrown against the ceiling and onto the floor like Caillou does to her.
"Dora Makes A Fake Lockdown". In the video, Dora disguises her voice as the school principal's (by pulling and hitting her own vocal cords, which right off the bat should've rendered her mute) and falsely announces over the intercom that a killer is inside the school. In the aftermath, Ricki Durundith, one of the parents of the students, announces that because of Dora's little "prank", her daughter apparently developed PTSD, is now in a mental institution in a padded room with an oxygen mask, a straitjacket, and a neck brace and a spinal board despite the trauma being mental. She somehow also had a compound femur stress fracture (which the maker of the video clearly misunderstood the meaning of as "stress" means physical stress) and is now paralyzed (which doesn't happen immediately. If it did happen, she would be paralyzed from the legs down and would be confined to a wheelchair at worst) in some sort of "stretcher pulse oxygen mask machine" forever. She now also has frequent seizures (which can't occur from PTSD, you either have to be born with it or suffer a severe head injury) and has to see nine physical and behavior therapists, and to top it all off, this will all cost an absurd $900,000 (which Dora's family will have to pay) and apparently the incident torn apart the family. All just because of an announcement. A YouTube comment even called this out:
maltheopia: Dora probably got a beating after, as Veena said, they got saddled with huge bills. Of course, who needs almost that much money in medical treatment for a scary prank? I think Ricky's parents were running a scam.
In fact, the WMG page has a theory that Ricki was lying about the whole thing to scam Dora's parents out of their money.
"Dora Pranks the Pizza Guy" (and other videos like it) has a part where, after the person whose vehicle is stolen by the eponymous troublemaker is run over by them, is immediately rushed to the hospital. Even though it is understandable that the character would receive bone fractures, one of the injuries of the character are fourth-degree burns (which are a very rare occurrence in real life, and are often near-fatal) all over their body (which cannot happen from being struck from a speeding car, and said character was not near fire at the time), alongside the doctors using a power drill to drill holes into his body (this would cause a mass amount of blood being shed, which would in term lead to the character dying in the process). The results of this leave the character in a body cast (represented by a stock image that does not resemble the character at all) a la Evel Knievel.
In "Sophie Fakes Sick and Gets Grounded", Sophie is healthy, yet her temperature is 71.1 degrees. If it's in Fahrenheit, that's way too low, whereas if it's in Celsius, that's way too high.
In Dora Causes A Car Collision, Dora gives her dad one alcoholic drink, and when it causes him to get in a car collision, he is considered legally intoxicated. In reality, while drinking does impair one's driving skills, it takes a few drinks for an adult male to be considered legally intoxicated, even if they are lightweight.
In "Caillou Throws Rosie Off a Plane", Rosie, while clearly in pain, still survives being thrown off the plane. In reality, a fall from that height would easily kill anyone unless the sudden stop was prevented somehow, but since Rosie appeared to have a fast, uninterrupted fall, she should have been dead.
In "Caillou Takes a Massive Pee", Caillou pees so much he floods the world. Needless to say, that cannot happen; the human bladder can only hold about a litre or so of pee before it ruptures, and a four-year-old's bladder holds much less.
(original video deleted, video part of compilation) has Caillou faking sick by showing his mother that his temperature is 103°Fnote after holding it in hot water. Later, his mom takes his temperature again and discovers Caillou's actual temperature is...70 degreesnote . That's actually a dangerously low temperature for anyone's body to be at (Hypothermia starts below 95°Fnote ), and yet Caillou is shown perfectly healthy.
