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 ↷ 跳 repeatedly — essentially allowing unlimited multi-jumps while within liquid. The Flipper is found in Water Chests, which are found submerged in water. They can also be found in an Ocean Crate.
- On the 移动版, wearing the Flipper will also allow the player to travel through water without slowing down, just as the Flipper Potion does.
