Pokémon Sword and Shield has an even rarer type of shiny to collect

Everyone knows that Shiny Pokémon are supposed to be rare — there’s only a 1 in 4,096 chance you’ll find a monster in a special color, unless you use a special method to increase your odds. But Pokémon Sword and Shield has introduced another type of Shiny to the mix, which, if found, will enter the battle with a slightly different type of animation.

Players are calling these ultra-rare monsters “square Shinies,” because their animations appear diamond-like, rather than the typical sparkles that you see for most Shinies. According to hackers who have looked at the files, there’s only a 1 in 16 chance your Shiny will be a square Shiny. Which, statistically speaking, means most people stumbling onto a Shiny will find the standard sparkles, not the square ones.

Here’s what it looks like in action — note that it’s a subtle effect, but still, it’s different.

The odds differ depending on what method you use to Shiny hunt. Random Shiny encounters and breeding have the 1 in 16 chance, but if you’re using the chain method to Shiny hunt, then the odds are inverted — there’s a 15 in 16 chance they’ll be squares.

For completionists who feel they need every single form of monster available for their compendium, this might sound like a nightmare. But, at least one Shiny hunter isn’t worried.

“For me it’s about the Shiny, regardless of Sparkles!” Shiny hunter aDrive told Polygon.
