Octozeppelin
From Inkipedia, the Splatoon wiki
Octozeppelins are large purple zeppelins that have Octotrooper faces sewn on the front and a large tentacle at the top, which is their only weakpoint. At the back of the zeppelin is a 
Sprinkler-like exhaust that spreads ink as it slowly flies. Some Octozeppelins spin as they fly, making it harder to shoot their tentacle.
