Toads Simple Origins: Fish Bowl

The mod adds custom piece armor and allows custom origins through datapacks, so a world can give players a way to spend more time in the water without removing the challenge of the land and the Nether entirely. Breathing underwater is the only change applied to the normal oxygen rules. A player who wears a filled fish bowl displays a HUD icon and begins tracking oxygen. A generated config file sets how long the oxygen supply lasts, and that drain time can be changed, with the maximum oxygen and a default of 6000 ticks (5 minutes). Config changes can be applied in a running game with the reload command.

Right-clicking with the item equipped while standing next to a placed block works differently from right-clicking while crouching, and the bowl switches between filled and unfilled states under different conditions. An origin can take damage from water like Enderian or Blazeborn players, using the origins:damage filled bowl power. The mod is open source under the MIT License and runs on Fabric for 1.21.1 only, with Fabric API required; latest file is 1.2.2, dated 2026-07-21. Because it changes oxygen rules, it has to be installed on both the server and every player's client.
