Splatoon 3's next Splatfest is in collaboration with the "Pokemon" series, the "Splatoon x Pokemon Collaboration Fest," which will be held from Saturday, November 12 to 14 at 9:00 (JST).
The keychains
The upcoming event will bring a collection of keychains, each displaying the same Water, Grass, or Fire-type logo we saw on the Splatoon X Pokemon T-shirts. The keychains will be purchased from the Japanese My Nintendo Store for 50 platinum points each.
