What you are looking at is a Game Boy hooked up to a nitrous oxide machine, so that this child can be sedated. It’s called the PediSedate and it’s probably a really bad idea.
The PediSedate was designed for use by dentists. Apparently they got bored with putting people under the normal way. The idea is to distract kids with video games while they are drugged for root canal surgery and such. That doesn’t seem creepy at all.
