Industrial Toast

Into the Octo Oven is the first boss mission in Splatoon 2's single-player mode, Octo Canyon.

First Phase
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 loaves won't immediately pull the bread back, giving the player time the 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 when enough damage is done, the player super jumps to the ground and the next phase begins.

Second Phase
The Octo Oven doesn't change anything about its attack pattern, but gushers firing Octarian Ink will appear, as well as a decrease in climbable walls.

Third Phase
The Oven will now extend a "glazing machine". If only uses this if you don't attack it with all its loaves out and when the third phase starts. It will turn towards you while the machine shoots out ink. The gushers are now strategically placed in areas that will get in the way of the player trying to outrun the machine. After when this attack is down, an extremely large portion of the arena will be covered in Octarian Ink. In additions, the pre-existing loaves of bread now have armored spots that are un-inkable and un-climbable and the bread comes out faster.

Trivia
This boss is very similar to the The Mighty Octostomp from the first game. Both bosses require you to climb up them to reach the tentacle, and they both try to reduce the amount of inkable surfaces.
