One year after mapping space, Flurry Heart and the Young Six have received a call for help from some possible new allies in the cities of Inkopolis and Splatsville. The Squid Sisters, Callie and Marie, have said their home cities were bombed and their parents and children have been captured. After calling some earlier allies out of retirement, everyone has arrived and is ready to carry out this dangerous rescue mission. Will they succeed?
