During chapter 3, Rose's Room, May and Cody will have to venture into a toy boat, when starting the adventure, you will be able to access a series of general instructions that will help you direct and fire your weapons. Which you can do with the left stick to move and R2 or RT to shoot.
When you start the battle, you will be trapped in a whirlpool from which you will have to shoot the bow of the ship towards the octopus and shoot non-stop to get out, which will reduce its health by half and start the second phase.
At this point its tentacle will come out of the water and launch rubber ducks at the boat, which you will have to destroy using the cannons and as it releases them in a circle you will have to move clockwise.
After the full rotation, the octopus will come out, so you will have to keep attacking with the cannon until the ship is in the air. Eliminate the floating tentacles while you finish off the toys on the right side. Repeat the process until you are able to finish it.
That's everything you need to know about how to beat the giant octopus in It Takes Two, so now that you have it, we hope you can take down this enemy quickly.
