Rivulet

''Breathes underwater, and moves through the world with ease. These adaptations are essential, as you'll be pitted against a world of increasingly frequent floods, where time is of the essence.''

The Rivulet is one of five playable Slugcats in the Downpour DLC. They begin the game with a swallowed pearl in Drainage System, and have a variety of unique mechanics, including greatly increased movement speed, swim speed and jump height, greatly extended breathing capacity underwater, and the ability to pop by holding it. Cycles are much shorter and shelter failures are more frequent in the Rivulet campaign, making Rain much more frequent.

Food
5 food pips are required to hibernate, while up to 1 may be stored for the next cycle.

Opening
The Rivulet's opening fades in to show a room in Drainage System. Two explosions are heard, before a dead and Rivulet fall into water from a shaft in the ceiling. Rivulet also opens with the mark of communication.

World Changes

 * Cycles are much shorter than usual, sometimes with only 6 pips (~3 minutes) of length.
 * Hard mode spawns are enabled. New water based predators are added and are more common.
 * The Monk and The Saint passages are disabled.
 * Brother Long Legs are close to, if not entirely absent from.
 * The water in Garbage Wastes and is now blue.
 * has been consumed so badly by the Rot that it's been renamed to . This altered and expanded region contains water sections where pipes have decayed as well as Brother and Mother Long Legs, with much of it having gravity anomalies.
 * Incidentally, the Rot has spread to as well, with Rot cysts like the  being much more common.
 * Pieces of the Underhang have fallen into the, spreading the Rot and the native fauna into the subregion, ironically making it slightly less dangerous than when the Miros Birds were around.

Standard
Rivulet is much faster than survivor at ~2.5x speed, also possessing increased jump height, swim speed and a very high back-flip.

Sliding
Rivulet has a very powerful slide, being able to traverse around 2/3rds of the screen at will. This is ideal for traversing flat areas quickly.

Spearing
Rivulet has difficulty getting spears to stick in walls, needing to stand very close for spears to stick.

Swimming
Rivulet can boost itself through water at high speeds and has overall significantly faster swim speed. Contrary to several in-game descriptions, they cannot breathe underwater and mearly have greatly increased lung capacity.

Crafting
Rivulet can pop Bubble Fruit by standing still for a short period of time without dropping it. This is independent from popping Bubble Fruit by submerging it in water, which will still remove the fruit from Rivulet's hands.

Tips

 * Ignore any fights that are not absolutly manditory. Due to short cycles, running fast between dens is the key. Your high speed means most predators cannot get a hold of you and most can be slipped past with ease. Wasting time fighting creatres will likely lead to running out of time. will struggle to grab hold of Rivuelt, so even they can be mostly ignored. As you cannot eat predators, the only benefit to fighting is for potential Passages
 * If a shelter failure occurs, you will have more time to get progress done. Beware that this prevents cycling at the same shelter. Take note of routes to previous shelters if needing to build up Karma.
 * Although having high lung capacity, you are not amphibious. Make good use of and  around very flooded sections as despite appearances, drowning is by far the most dangerious threat to Rivuelt
 * Scavenger Tolls flee when the rain is close, making it easy to slip past with enough time to reach the next den.
