As part of the various Splatfest events in the Splatoon series, Nintendo releases official art. So for Splatoon, we’d see the Squid Sisters Callie and Maries engaged in activities for the festival, and so on. Now Nintendo’s Japanese branch released a virtual gallery online that shows the imagery created for all three games’ special events.
The official site doesn’t show the winners for the Splatoon, Splatoon 2, and Splatoon 3 Splatfest events, only the art. Each one shows what the question was for that one, as well as what the two sides were. In the case of situations where there were different topics, there are buttons that you can click to see the different options. For example, the July 2017 Splatoon 2 Splatfest was Rock vs Pop in Japan and Cake vs Ice Cream in North America, Europe, and Oceania. So if you scroll to that event in the virtual gallery, it initially shows Pearl and Marina with the Rock vs Pop art, and clicking the button for other regions shows the Off the Hook members with cake and ice cream.
The gallery also covers art from special collaborations as well. For example, there is the image for the May 2018 Sanrio Splatfests. The Deep Cut The Legend of Zelda Splatfest imagery showed up as well.
Splatoon is available on the Nintendo Wii U, while Splatoon 2 and 3 are on the Switch.
