So, that’s a headline I didn’t expect to write today, but hey. It’s Nintendo Switch launch week, and here’s a public service announcement – don’t put one of its game cartridges in your mouth. Not that I’m implying you would have otherwise, obviously. Are you three? Because that’s the real problem, apparently.

According to multiple serious investigative journalism reports in the gaming press, the cartridges taste super disgusting.

“It doesn’t hit you at first. It tastes just as plain and feels just as slippery as the other three cartridges. In just a few milliseconds, though, a very sour taste invades your taste buds. It smells bad; you can feel it in your throat,” Polygon’s Julia Alexander describes it. “It’s revolting, and the only thing I can equate it to is when you’re at the dentist and a drop of sour cleaning material hits the back of your tongue. Your entire face feels it. And the taste lingers for about 20 seconds.”

Because why? Because it’s supposed to, apparently. Responding to a query from Kotaku, a Nintendo rep explained that there’s a chemical on the cartridge labels, to prevent kids from eating them.

“To avoid the possibility of accidental ingestion, keep the game card away from young children. A bittering agent (Denatonium Benzoate) has also been applied to the game card. This bittering agent is non-toxic.”

Millipedes taste terrible too, but that didn’t stop me when I was three. And I’ll tell you what – I didn’t ever eat a millipede again. I still remember exactly what it tasted like too. Yuck.
