The Flipper is an accessory that allows swimming in water and lava by repeatedly hitting the jump key. They are found in chests, with an increased chance of being found in underwater chests. The flipper will allow you to travel through water without using a Grappling Hook or Ivy Whip. The Flipper can also be combined with the Diving Helmet at a Tinkerer's Workshop to make the Diving Gear.
- The effect of the Flippers is also given by the Flipper Potion.
