How to Beat the Whale Boss - How to Fish Solo Final Boss
The best single video for this page because it keeps the two fights separate instead of cutting straight to the lava whale: preparation first, then the normal Bowhead Whale, then the mutated phase. Watch it if the crater step is the part confusing you.
Focused only on the lava whale, so it is shorter than the full-route videos if the first whale is already behind you.
