Octostomp

"I'm BAAAAAAAAACK!"

- The Octostomp at the beginning of The Octostomp Returns mission.

The Mighty Octostomp is a one of the first Great Octoweapons encountered in Octo Valley and later reappears in Octo Canyon and Octo Expansion.

Background
The Octostomp was an Octoweapon created during The Great Turf War by the Octarians. When it seemed that victory had smiled upon the Octarian army, a plug was pulled and caused the Octostomp and the rest of the Octarian mechs to shut down. Nearly 100 years later the Octostomp was brought back to life by the power of a Zapfish in order to attack once again.

Appearance
The Mighty Octostomp is a robotic Octarian in the shape of a large cube with several layers on its Octotrooper-like face covered in purple ink. It has 9 metal panels on most of the sides other than the front and bottom, and has a hole on its back where a tentacle can grab Zapfish. It also has two Octarian feet that somehow are strong enough to make the Octostomp jump. In the second game the Octostomp is given a ink-proof jacket that appears to be made of thermal fabric along with a rubber belt.

Splatoon
In Splatoon, the Octostomp is the first boss Agent 3 incounters. It appears in the mission "The Mighty Octostomp!" where you have to dodge its attack and climb up its body to splat the tentacle. Each time it will remove several panels from its body making it harder to climb. Once Agent 3 has splattered the tentacle a third time, Octostomp will be defeated and explodes.
