I'd like you to picture it for a second - you're playing Demon's Souls, and a looming shape appears in the distance, obscured by fog. By the time you get close enough to see its beak, it's too late. The giant rubber duck has already eaten your character whole, proclaiming its victory with an earth-trembling squeak. The "You Died" screen quickly follows. Of course, this isn't a reality, but at one point during its development, rubber ducks were in Demon's Souls, although just as a testing tool.

This development quirk was revealed by Collin Harris, a former technical artist at Bluepoint Games. On Twitter, Harris shared a video of one of the game's downtrodden, heavily armored player characters rolling through a wooden bench and table. The environment objects broke apart as you'd expect, but with one addition, a bunch of small, brightly colored, ducks. The camera turns behind the player character immediately after, showing a much larger duck sitting in the distance, obscured by fog.

While it would have been wonderful for these rubber ducks to end up in Demon's Souls as a secret enemy, its fate wasn't that glamorous. In the same thread on Twitter, when asked what happened to the adorable testing objects, Harris said that they had been completely removed. "Sorry to disappoint, but all the stuff you see in the video (including the test room and duck) was temp and didn't make it anywhere near the finished game," replied Harris. It's just a shame that there wasn't just one rubber duck behind the game's previously locked mystery door.
