The Boss Kettle for this boss can be found in the middle of Tentakeel Outpost, on a pyramid-like hill.
Phase 1[edit]
The Octo Oven will try to line up one of its loaves at the player. The boss will then extend it, and quickly retract it. The Octo Oven does this multiple times until it does a short hop and extends out all its loaves. The Oven won't immediately pull the bread back, giving the player time to ink them and jump from loaf to loaf to get to the tentacle at the top of the oven. The player needs to fire at the tentacle to deal damage. After enough damage is done, the player Super Jumps to the ground and the next phase begins.
Phase 2[edit]
The Octo Oven doesn't change anything about its attack pattern, but ink pistons firing Octarian ink will appear, as well as a decrease in climbable walls. The ink pistons will break if bread hits them, but will be added back when the Octo Oven's attack loop repeats.
Phase 3[edit]
The Octo Oven will now extend a "glazing machine". The glazing machine will rotate around most of the arena and will give chase to the player while spewing out ink. The ink sticks are now strategically placed in areas that will get in the way of the player trying to outrun the machine, and will retract to not get hit by the glazer. After this attack is over, an extremely large portion of the arena will be covered in Octarian Ink. In addition, the pre-existing loaves of bread now have armored spots that are uninkable and unclimbable and the loaves come out quicker.
