Once a fountain has been activated, vaccing up some water from it will grant the ancient water effect. The water tank HUD will have a rainbow effect applied to it, and the water tanks stack number will be replaced with a timer counting down from 29 seconds. During this time, Ancient Waters supply is unlimited and the water blobs have a subtle rainbow sheen, which leave sparkly particles when it comes into contact with a surface or a slime. Any Tarr hit with Ancient Water is obliterated regardless of the time of day. When the effect wears off, it will leave the water tank with normal water at maximum capacity.
When initially visited, they are inactive. They can be activated by looking for three Slime Statues nearby – which represent a certain type of slime – and depositing their associated plort into it. When all three statues are active, the fountain will activate and will be able to grant the player the Ancient Water effect by sucking water from it, although a Water Tank is essential to be able to do so. Ancient Water can be used to rejuvenate Oasis buds into fully fledged oases. You have 30 seconds to plant oases until the water tank will have normal water again.
