Splatoon
In Splatoon the Slosher is a bucket of ink that can be swung to splatter turf and enemies in a straight line. The trajectory of the ink can be adjusted to strike enemies behind walls. It's strong enough to splat opponents in only two shots, and comes in a set with the and.

"A weapons-grade bucket that hurls ink straight ahead over an impressive range. By adjusting the angle, it can be used to hit opponents who are up high or even on the other side of a wall."

- In-Game Description

"This might look like an ordinary bucket, but it’s actually a weapons-grade bucket! Hurl ink straight ahead over an impressive range, and adjust your angles to hit opponents above you or behind walls. The Slosher comes with Burst Bombs and the special is a hot pastrami on rye! Er, wait. Sorry. I mean Inkstrike. Got a little excited about today’s lunch delivery."

Note

 * The Slosher deals more damage the farther away the ink travels, as opposed to Rollers and Shooters dealing less damage the farther the ink goes. In addition to this, more ink will be spread the farther away the ink travels, allowing for an easier time to hit targets. A close arched shot will deal 40 damage with no Defense Up or Attack Up perks, and a far arched shot will deal 70 damage. However, the Slosher will always deal 70 damage no matter the range if a direct shot is hit.
