Tentakeel Outpost

Tentakeel Outpost is the first sector of Octo Canyon in Splatoon 2. It holds 3 Kettles and 1 Boss Kettle and is the only sector to hold a small fort and an Ammo Knights Enhancifier with which to upgrade Agent 4's Main Weapons and purchase Sub Weapons. Starting from the Version 3.0.0 update, after the player beats the final boss of Octo Canyon and subsequently enters Tentakeel Outpost for the second time, Callie will appear at Cuttlefish Cabin, alongside Marie. Players can join the Squid Sisters' conversations, and hear their stats from the last 50 multiplayer battles from Callie.

Missions

 * Mission #1: Return of the Octarians
 * Location: In front of the Boss Kettle


 * Mission #2: Welcome to Octopia
 * Location: Surrounded by a fence of Grates in a corner.


 * Mission #3: Sunset Octocopter
 * Location: The path is blocked by a stack of small boxes. Shoot at the boxes to reveal the path and there is a kettle sitting at the center of the octagon.


 * Mission 1B: Industrial Toast
 * Location: Passing the hallway, there is a Boss Kettle found in front of a ledge.

Sardinium
Climb up the wall to the west of the Boss Kettle. There is a small box on the small tower. Break it to reveal the Sardinium.

Sunken Scroll
A Yellow Balloon can be found south west to the Boss Kettle. When the game tells Agent 4 to follow the balloon, this means that this balloon is a Sunken Scroll Balloon. The second balloon is close to the small tower. The third and fourth balloons are near the Boss Kettle. The fifth balloon is next to the kettle to the first mission. The sixth balloon is between the second and third mission kettles, but at a high altitude. Climb the wall to reach the balloon. The seventh and last balloon is on the set of platforms adjacent to the wall. Once all seven balloons have been popped on time, the sunken scroll will appear on the set of platforms.

Trivia

 * There are a couple of parabolic antennae around Tentakeel Outpost with the text "Ikavision" written on them, which makes it one of the few in-game appearances of any written human language outside Splatfests.
 * The caged insect from Marie's Grasshopper vs. Ant Splatfest artwork can be seen next to Cuttlefish Cabin.
 * On the side of Cuttlefish Cabin there is a phone that looks like the Telephone from the Octo Expansion.
