He included pictures of Peppa's right face and Peppa's left face, before revealing her "front face" — which includes four eyes and four nostrils.
He later followed up with a colour version of the image, and Peppa fans were left distraught.
"Peppa pig is on in the waiting room we're sitting in, and I can't unsee that left face/front face/right face drawing," one tweeted.
Another said, "The front face of Peppa Pig makes me uncomfortable."
A mother of two suggested that "you probably shouldn't show your kids Peppa Pig's terrifying 'front face'".
And another Twitter user declared it was "the stuff nightmares are made of".
