Some sort of document relating to Doki Doki Panic. I think that’s the instruction manual open over on the right. Note the drastically different character art for Birdo. I’d be interested if anyone who can read Japanese can tell me what’s gong on here, or why Mario might me appearing alongside Imajin in the logo on the left.
I wonder if perhaps Mario is just there for the sake of showing people that it was a Nintendo game, or so people didn’t get turned off by unfamiliar characters.
