After gathering these ingredients, you will need to get one more ingredient, which is the Coral Tree Sap. Follow Cho Oyu, and she will get the sap from the Coral Tree. She will then create the potion. Once the potion is done, you will be asked if you’re prepared to take it.

Once you take the potion, you will be taken to the customization screen, where you can choose how your lower merfolk half will look like. Your transformation will then be completed after you make your choice. Your merfolk form will be your new form whenever you are underwater, removing the need to wear the diving suit, and then you will switch back to your human form once you get back on land.
