The Octonozzle was an Octoweapon created during The Great Turf War by the Octarian army. When everything looked victorious for the Octarians, a plug was pulled and caused the Octonozzle and the rest of the Octo Weapons to shut down. Nearly 100 years later the Octonozzle was powered up again by a Zapfish stolen by DJ Octavio in order to defeat the Inklings and claim the surface.
The Octonozzle is awakened when Agent 3 arrives to its Kettle in Sector 2. It will then attack by shooting balls of Ink from its "nose" until Agent 3 pops all the suction cups to reveal the weak point. It will then lift its body up one in order to make it more diffucult for 3 to pop the targets. After splatting the tentacle three times, Octonozzle will be defeated and then explodes.
