The Ocean Title Deed is a claim to the Deku Flower located inside Lulu's room at Zora Hall. If Link approaches the Deku Flower, a Business Scrub will pop out from it. If Link speaks to the Business Scrub as a Goron, the Scrub will inform him that he is interested in moving to Goron Village, where the air is clean. If Link presents the Mountain Title Deed, the Business Scrub will offer his own Deku Flower in return. If Link accepts, the Business Scrub will give Link the Ocean Title Deed and leave for his new Deku Flower in Goron Village.
With the Ocean Title Deed in Link's possession, he can freely use the Deku Flower in Lulu's room to fly to a ledge in her room. Link can alternatively repurpose the Ocean Title Deed as toilet paper by giving it to ??? in the Stock Pot Inn's bathroom after midnight each night. Link can also trade the Ocean Title Deed to the Business Scrub outside Sakon's Hideout in Ikana Canyon in exchange for a Huge Rupee and the Deku Flower he has claimed. However, if he does so, the Business Scrub will move to the Deku Flower in Zora Hall and Link will not be able to access it.

Actually, I'd like to do business someplace where it's cooler and the air is clean. But to open a business in another place... You need to go through the proper channels first. Do you know what I mean?" — Business Scrub (Majora's Mask 3D)
