You would be hard-pressed not to equate this weapon to a normal human bodily function, but the jokes stop there. Stream can deal serious damage with the right touch, with twenty projectiles dealing 4 damage a piece. Stream, Creek and River should ideally be fired at an angle of 45 degrees, when firing from a flat surface with no obstacles in the way, because this drastically minimizes the spread leading to much more damage.
"Creek" is basically a body of running water leading into a larger body of water. It's also the sound the door of winning opportunity makes for you when you shoot it accurately. Twenty projectiles dealing 6 damage a piece sure will drench the fiery burning sensation your opponents will feel when their tank explodes.
River cannot exactly be explained as a "weak" weapon. Matter of fact, it just plain isn't one. River can do it all: Spread wide enough to cover large areas, do a great deal of damage to one or more tanks, and remain easily accessible as a weapon you'll unlock rather quickly. Twenty large projectiles scatter about to deal 8 damage a piece for a monstrous impact. Given its high spread, it's best to fire this weapon at 50-55 degrees, otherwise the weapon will not concentrate much firepower. It is to note that this weapon will never achieve its full damage under most, if not all circumstances.
Oh, what's that? River isn't enough water? Twenty projectiles isn't enough? Well, while Tsunami does not deal as much damage as River, it does provide a nearly-direct stream that slowly moves up like a tidal wave. Fourty-eight projectiles dealing 3HP damage a piece may make you evacuate the game itself in pure terror.
The spread from this weapon is caused by each projectile being shot with a varied angle, similarly to Flame.
Stream, Creek, and River can be effectively used at close range against a single target when used with angles around 45 degrees, as this shot allows most the projectiles to hit a single target, as long as they're on the same level as you.
Tsunami's shots differ in power, meaning it's most effectively used at high power and low angles
