For those who want to go swimming in Cadence of Hyrule, we do have a guide for you.
The Flippers, or Zora Flippers as they are also known, are one of the key items in-game that you must find to complete the game. They relocated in Lake Hylia in a small cave where the Prince of the Zoras sleeps— and you need to wake him up.
To do so, all you need to do is find the ghost in the room that speaks back to you and drops a bomb at his feet. He will then go hostile, and it’s up to you to kill him in a small, if not annoying, battle. Once defeated, the Prince will wake up and reward you with the Zora Flippers for saving him.
If you want to get the Snorkel as well, which goes alongside the Flippers and lets you dive, you can find that item to the very south of the map in a Beach shop near the centre. It’ll cost you 80 Rupees so make sure that you have the money on you.
Then, you should be all set to take on the dungeon in Lake Hylia and bring you one step closer to completing the game as either Link or Zelda.
