A step beyond the simply pirated Peppa Pig videos mentioned previously are the knock-offs. These too seem to teem with violence. In the official Peppa Pig videos, Peppa does indeed go to the dentist, and the episode in which she does so seems to be popular — although, confusingly, what appears to be the real episode is only available on an unofficial channel. In the official timeline, Peppa is appropriately reassured by a kindly dentist. In the version above, she is basically tortured, before turning into a series of Iron Man robots and performing the Learn Colours dance. A search for “peppa pig dentist” returns the above video on the front page, and it only gets worse from here.
Disturbing Peppa Pig videos, which tend towards extreme violence and fear, with Peppa eating her father or drinking bleach, are, it turns out very widespread. They make up an entire YouTube subculture. Many are obviously parodies, or even satires of themselves, in the pretty common style of the internet’s outrageous, deliberately offensive kind. All the 4chan tropes are there, the trolls are out, we know this.
This is completely scary. Absolutely no more YouTube. Something is indeed wrong on the internet. Read the really long post. It's scary in all aspects.
