The Doki Doki Panic sequels
A beautifully committed April Fools bit: what if Doki Doki Panic got the same sequel treatment Mario gave it, but in reverse? So there’s a Doki Doki Panic 3, a Doki Doki Panic 64, and so on—each one a reskinned Mario game, presented with a straight face as a genuine series retrospective. The mock-ups are genuinely impressive.
