Unidentified Flying Object

Unidentified Flying Object is the ninth mission available in singleplayer Octo Valley. It is the first mission with an Octostriker, an Octarian enemy that launches Inkstrikes, and takes place in a modified version of the Tutorial Area.

Octo Valley
After beating The Mighty Octostomp! in World 1's Boss Kettle, the player can move on to World 2 via an Inkrail near the Boss Kettle. This level's Kettle can be found by inking a wall near the left side and then jumping one platform to the one where the kettle is.

Walkthrough
Beginning

Once the player walks a few yards out of the Spawn Point, the Octostriker (resting in a pool of ink in a UFO) will notice the player and shoot a missile. To avoid it hitting you, shoot some ink down on the surface and hide, as the missile will not strike if they do. Since the first Checkpoint is nearby, use a Seeker to get there without being spotted.

Checkpoint #1

Near the player are Squee-Gs with Power Eggs on them. Grab the Power Eggs and turn into Squid form to get to the other side of the wall, as a pre-inked path of the player's ink color is nearby.

Checkpoint #2

Several Octodivers hide in the ink around the skateboarding area, so make sure to use Seekers and take them down. Once the player gets to the slopes, a Twintacle Octodiver is hiding, so take it down too. Make sure to also throw Splat Bombs at the trees as Power Eggs are in them.

Checkpoint #3

The player should use the Gusher nearby and then throw a bomb at the ink puddle on the platforms to defeat the Twintacle Octodiver in it. To find the Sunken Scroll, go behind the platforms and shoot the box to obtain it. Jump across the yellow grated walkway to get to the next checkpoint.

Checkpoint #4

Try not to get too close to the grated wall as two Octodivers rest in the ink, but the player can throw a Splat Bomb to defeat them. Once the player defeats them, jump off the platform onto the UFO crash site. Make sure to use Seekers once more as more Octodivers are around here.

Checkpoint #5

Throw a Splat Bomb at the crates to destroy them. Now splat the wall and then use the Balloon Fish to climb the next wall and defeat the Twintacle Octotrooper. Once the player climbs up the wall and defeats the last Twintacle Octotrooper, they can now jump to the UFO to encounter the Octostriker.

Final Checkpoint

The Octostriker will summon 3 sets of Octocopters which will all respawn about three times until defeated. While defeating them is optional, the player must continue splatting the Octostriker until he gets splatted. Once this happens, an explosion occurs, releasing the Zapfish from the purple ink. Level complete.
