Squidbeak Splatoon

The Squidbeak Splatoon was a platoon of soldiers who fought against the Octarians during the Great Turf War. It was led by Cap'n Cuttlefish, and its members included Ammoses Shellendorf, Judd, a male Inkling, and a female Inkling. The group used Bamboozlers in combat.

New Squidbeak Splatoon
The New Squidbeak Splatoon was formed by Cap'n Cuttlefish after the Great Zapfish was stolen by the Octarians. He recruited his granddaughters, Callie and Marie, into the platoon to search for the missing Zapfish, and later persuaded Agent 3 to join the platoon as well. The New Squidbeak Splatoon successfully defeated the Great Octoweapons and DJ Octavio on two different occasions, recapturing the stolen Zapfish and restoring power to Inkopolis.

Agent 3 defeated the Great Octoweapons and DJ Octavio, recapturing stolen Zapfish and, eventually, the Great Zapfish along the way.
