Inner Tube

The Inner Tube is an accessory that causes the player to float on the surface of liquids instead of sinking to the bottom. The effect can be temporarily negated by holding. It can be found in Water Chests, as well as Ocean Crates and Seaside Crates.

Tips

 * This can be further exploited using Lances to cause extraordinarily high damage, with the potential to inflict 1 million damage in a single hit.
 * Once the player reaches speeds of around, they will start to phase through blocks and ignore the Portal Gun's portals, but not Teleporters.
