Just a single Octoling took the Great Zapfish from Inkopolis and Cap'n Cuttlefish decided to try and take it back but However he only had his Grandaughters(Squid Sisters) and an unnamed Inkling so he decided to take some help but nobody wanted to help except for the Sunshine Realm but the Sunshine Realm could only help them if he promised from Swag King Boo to give Inkopolis and any other of its surrounding places as territories of the Sunshine Realm.
