After talking with him, he’ll hop on your back and you’ll need to take him to a special spot in the Flooded Fortress. If you go into The Stranded Sailor, you’ll see Jefferson the squid sitting in a tank with a collapsed body next to him.

Use the key to access the locked tower, climb up, and strike the bell with your weapon. Once you have it, go to The Lost Cemetery, and head all the way north, above the entrance to the Estate of the Urn Witch. This will be sitting where you fought and killed the final boss.
