Splattershot Jr.
From Inkipedia, the Splatoon wiki
The Splattershot Jr. is a Main Weapon in Splatoon. It is in a set with the Splat Bomb and Bubbler. It is ideal for covering large territories with ink quickly--it's low accuracy provides a wider spread of ink while moving, and its low damage means it uses less ink per shot, allowing for more shots per tank. The splat bombs and bubbler help counter the lower damage output by adding a good offensive option and a strong defensive one, respectively. Add to that the bubbler's ability to shield nearby teammates as well, and the Splattershot Jr. is an ideal support weapon.
