The Animal Crossing series has a history of constructing an entire simulated TV lineup, viewable solely within their games. Each program is usually only a short midi loop, some overlaid fake dialog, and an animated GIF, but the complete schedule is fairly impressive.
At 3:33 AM on Sunday and Monday mornings, a one-minute program plays, depicting a UFO and an alien addressing the viewer. The lead-in and lead-out are the simulated broadcast static for the 3AM block. It’s easy to miss, and it’s even easier to think it all a fabrication through sleep-addled exhaustion.
In other words: conspiracy theories. For kids.
