The Sloshing Machine is a Slosher that resembles a washing machine, hence its name. It has a revolving drum, just like in a washing machine, which spins the ink rapidly, creating a missile-like projectile.
"An innovative new weapon that puts a "spin" on the classic Slosher model. The Sloshing Machine is sure to make your whites whiter than white and your turf inkier than inked! This weapon's attractions are the power of the main shot and the bonus ink flung out by the vortex. The Splat Bombs and Bomb Rush combine to send the battlefield into a whirlpool of confusion!"
