The repeated stealing of the Great Zapfish and the kidnapping of Callie happened in Splatoon 2.

Yes

hey bro, did you invite me to mod a stream?

What stream?

See that's the thing, I got a notification saying that you invited me to mod your stream, but I didn't understand it.

For some reason the great zapfish disappearing does not effect inktropolis in any way and I pmly want to take down octoranians because they kidnapped callie
