Roller

Rollers are one of the five main weapon classifications in Splatoon. The Roller easily spreads ink over a wide area around the user, making it an ideal weapon for inking on the go. For most rollers, running into enemies will instantly splat them, changing the splat cam message from "splatted" to "squished". For attacking enemies out of melee range, rollers also have a mid-range ink-flinging attack.

With the Inkling Boy amiibo, the player can use a Roller for Octo Valley missions.

 * There are no rollers with Point Sensor ,Toxic Mist, or Disruptor as their sub weapon.
 * In the corner of the Shooting Range are some parts for a roller, most likely a Splat Roller.
 * Because rollers are big, parts of them will sometimes go through walls as it is bring pushed.
 * Rollers are not affected by Run Speed Up.
 * All rollers in the Octobrush series and the Inkbrush series as well as the Coro Coro Splat Roller are the only Roller class weapons that have not gotten nerfed as of January 2019
