Every so often in video games, there are unintended gameplay mechanics uncovered that end up being unspoken tips of the trade, just as with this likely bug in Pokémon Brilliant Diamond and Shining Pearl that most players are viewing as an "unpolished feature."
Thanks to this clip discovered on Reddit, it seems that walking with a Pokémon can reveal hidden items.
Following Pokémon Can Reveal Hidden Items in Pokémon BDSP
On Nov. 23, a Redditor by the username of u/iwillblastufat posted a thread to the r/pokemon Subreddit titled, "Pokemon have collisions with hidden items!"
In just 20 seconds, the clip displays the hidden utility in action, as their Naruto-running Empoleon awkwardly gets stuck on an invisible wall while they continue to run into the building ahead.
While it does look incredibly busted, the player soon made a U-turn to investigate the issue and was greeted by a free hidden bottle of Calcium.
Soon enough, while most on the Reddit thread agreed that this is definitely a handy feature to keep in mind moving forward, it also almost certainly has to be a bug.
Others specifically pointed out that this "makes up" for the clunky in-game dowsing machine, which players had been opting to just find hidden items by using third-party websites instead of going through the hassle of the official mechanic.
