Splat Charger
From Inkipedia, the Splatoon wiki
The Splat Charger (Spraytan or Compact Spraytan in several versions)is a Main Weapon in Splatoon. It is in a set with the Splat Bomb and Bomb Rush. Unlike most weapons, the Splat Charger can be charged. The more it is charged, the farther the ink will go. It also creates a thick line of ink, rather than a blob. This weapon is the most basic form of a Charger-type of weapon in Splatoon.
