If you were basing your real-world knowledge of hedgehogs on Sega’s Sonic the Hedgehog, we’ve got some bad news for you: everything you thought you knew about hedgehogs is wrong.

It’s been proven by Science and Mashable’s The Watercooler, which created a real version of a Sonic course to be run by Elvis, a hedgehog who lives at the San Diego Zoo. The results are shocking: Elvis is slow as molasses, terrible at jumping and seemingly straight-up bored of pixelated golden rings.

Guess it’s time America’s public schools update their textbooks when it comes to hedgehogs. Our children need to know the truth.
