If you saw Magikarp, the famously weak fish Pokémon, trending on Twitter last night it was for good reason. From January 1st through 3rd, Sword and Shield players will have a higher chance of encountering Shiny Magikarp in Max Raid Battles in the Wild Area to commemorate New Years. Magikarp in general will appear more frequently in Pokémon Dens during this limited time, giving players many opportunities to encounter Magikarp in its Shiny form.

Hey, Trainers! Have we got a deal just for you!

January 1–3, you’ll have an increased chance of finding Shiny Magikarp in Max Raid Battles! And it won’t cost you anything. 😉

Finding Shiny Pokémon is typically a rare occurrence—specifically, the chances are 1/4096. The Pokémon Company didn’t officially specify how much the odds have been increased, as they simply said players “have a much higher chance than normal” of encountering Shiny Magikarp. However, Serebii.net, a popular Pokémon fan site, has calculated that players have an 8% chance of encountering Shiny Magikarp.

Basically, 8% of the event raids you’ll see at the moment in each star category will have a guaranteed Shiny Magikarp https://t.co/oJsGRrRxym

The increased chances appear to be working for many players already, as people reporting their Shiny Magikarp findings got Magikarp trending last night.

This is the first time I’ve ever encountered a shiny Pokémon that wasn’t one the game gives you. And out of all the Pokémon in the world it was a Magikarp. I’m incredibly happy but also mad.
