You’ve seen pictures of them around—of course you have. Those tiny little Switch cartridges are remarkable pieces of technology, containing massive storage capacity inside a piece of plastic smaller than the cartridges even for your 3DS.
It’s great, and it’s going to make carrying around multiple games that much easier, but Nintendo understands their audience in a way that we didn’t anticipate—they realized that these little rectangles might be tempting targets for tiny hands.
So, thinking that babies and young children might be enticed to stick a game cartridge inside their mouth, Nintendo has literally coated every game card with a disgusting tasting coating. Don’t trust us? Please do, it’s not worth licking your cartridge for Breath of the Wild. But in case you’re still skeptical, yes, this is a real thing Nintendo has consciously done for the benefit of small humans’ safety:
“To avoid the possibility of accidental ingestion, keep the game card away from young children. A bittering agent (Denatonium Benzoate) has been applied to the game card. This bittering agent is non-toxic.”
So, don’t put it between your lips or teeth to swap out cartridges, is all we’re saying. You’ve been warned.
