This is a Game Boy hooked up to a nitrous oxide machine. It’s called the PediSedate. Nope, nothing sketchy about this.
The PediSedate was designed for dentists, allowing them to distract kids with video games while they were drugged in prep for oral surgery. But hey, why limit it to dentists? You could use this to sedate children for any number of reasons! And with a name like PediSedate, you get all sorts of great ideas right off the bat. I’m so surprised this never caught on.
