When used, it continually sprays ink in a circular ring around itself, in a staggering motion, until it breaks. It can be thrown onto virtually any surface, including ones that are upside-down. If the user throws another sprinkler with one already in use, or the user is splatted, the first one will automatically break.
Throwing it where Inklings usually pass by forces them to use a small amount of ink to clear the area up.
As it allows you to throw it onto upside down surfaces, throw it upside down as the shower of ink may damage and confuse Inklings.
Throwing it on hard-to-reach areas such as the moving platform on Saltspray Rig will allow it to ink more turf and be harder for enemies to destroy.
The Sprinkler can also be used to distract opposing Inklings, giving its user an opportunity to attack while their focus is on the Sprinkler.
It can be used as a shield. Throw it down, and shoot over it.
Shooting the sprinkler will cause it to break. Make sure to shoot any enemy sprinklers in sight, as they will continue spreading ink unless you destroy it.
If you are using a short ranged weapon, watch out for opponents near the sprinkler
