Animation Domination High-Def is literally dumping on Sega’s mascot. Scientifically Accurate Sonic the Hedgehog reveals hedgehogs defecate while running then recharge by eating the feces of other animals. They chew it into a paste that they rub on their body. They even eat their own children and its so-called friend Tails the fox eats hedgehogs. Like all videos in the Scientifically Accurate series it ends with a disturbing penis fact.
“Knuckles is an Echidna. They can’t fly. Don’t have a punching claw,” the song explains. “But they’re known for having a four-headed dick. It’s the only one like it. Scientifically accurate!”
Knuckles’ penis blows them away like the spinning blades of helicopter (not scientifically accurate). The penis is censored unlike most videos in the series such as Scientifically Accurate Ninja Turtles, which features super-sized erections. Fortunately, you can see the real thing in actual scientific video, and it’s even weirder than you can imagine.
Only two of the Echidna’s penis heads work at a time. The revelation was made by Steve Johnston of the University of Queensland in Gatton, Australia. Johnston inherited a frisky zoo animal that had to retire because it became erect whenever handled, making it easy to study the natural mating habits of the animal.
“When we tried to collect semen by [electrically-stimulated ejaculation] before, not only did we not get a single drop, but the whole penis swelled up to a four-headed monster that wouldn’t fit the female reproductive tract, which has only two branches,” Johnston told New Scientist. “Now we know that during a normal erection, two heads get shut down and the other two fit.”
