Original post: Halloween is fast approaching and it looks as though Nintendo will be celebrating with a special event in the excellent Splatoon 2. The news was discovered by dataminer Ink Larry on Twitter and he has found a logo for Splatoon 2 Splatoween amongst other things. Nintendo will presumably announce the event fairly soon.
There are also special icons that can be seen during x10 and / or x100 battle intros. pic.twitter.com/7TfRtPpUuh
