The Flipper is an accessory that allows a player to swim in liquid. With the Flipper equipped in an accessory slot, the player can swim upwards in Water, Lava, or Honey, by pressing the jump button repeatedly — essentially allowing unlimited multi-jumps while within liquid. The Flipper is found in Water Chests, which are found submerged in water.
- On the Mobile version, wearing the Flipper will also allow the player to travel through water without slowing down, just as the Flipper Potion does.
- 1.1: Can now be combined with the Diving Helmet to make Diving Gear.
