The Octo Oven is an Octo Boss that was created around the events of Splatoon 2 in order to be battled by Agent 4. Unlike the original four Octoweapons, it is accompanied by Octarians.
Appearance
The Octo Oven is a large oven with several Octarians inside of it. It also has a single glowing eye to watch Agent 4, along with wheels similar to those of a Flooder. It should also be noted that their are stickers on it that appear to be logos for an Octarian bakery. On top of it is a hole where its tentacle can pop out of.
The Octo Oven is the first Octo Boss that is fought in the Octo Canyon (mode). It will slowly surface from a large puddle of ink, starting the battle. It will attemp to hit Agent 4 with a one of the "loaves" until it gets fed up and shoots all of them out, this is 4's chance to climb up and splatter the tentacle. After this, the giant oven will remove several panels revealing an even bigger eye, three vents, and another pair of purple eyes. It will also shoot several "churros" from its top, and then continue its regular attack. In the final phase, it will grant the bread armor and will bring out a glazing machine to attack 4. Once defeated, the "bread" will shoot out burnt before exploding.
The Octo Oven returns in the Octo Expansion, known as the Octo Oven XXL, where it has been Sanitized and situated in Toastmaster Station. Its battle with Agent 8 is very similar to its last one with 4, where it constantly tries to hit its foe with the "bread". However, they are not alone, now there are several Octotroopers guarding the weak spot. Soon the Octotroopers are replaced with Octobombers, then later Octosnipers. After the tentacle has been splatterized thrice, the "bread" will burn and the Oven will once again.
