Goo Tuber

The Goo Tuber is a main weapon in Splatoon 2. This weapon can hold a charge for an exceptionally long time in comparison to other chargers, being able to hold a charge for 5 seconds as opposed to other chargers which only last 1 second. This allows players to get to a better vantage point or sneak up on enemies with a full charge. The weapon also bears the ability to store incomplete charges. Its charging time takes slightly longer than a, and the range is slightly shorter. Each fully charged shot consumes 15% of the ink-tank, allowing users to fire six shots before needing to refill.

The Goo Tuber is the only charger that can splat opponents with a single partially charged shot, as any shot charged at roughly 67% or more deals over 100 points of damage.

Etymology

 * Goo Tuber's Japanese name is "Soy Tuber". This weapon resembles a siphon pump aka shōyu pump (醤油ちゅるちゅる Shōyu Churu-churu).
 * Ever since the change made to the Goo Tuber in version 2.2.0, its minimal damage for a non-charged shot is 40.0 at 8 frames, and the theortical damage for a 99.99...% charged shot is 130.0 at 74.99... frames.
 * However, due to the game operating in complete frames, it is impossible to have a partial charge at any more than 74 frames, or 98.51% (66 effective charging frames out of a possible 67).
 * This also means that the minimal charge time for a one-shot kill is 53 frames (45 charging frames out of a possible 67), for a 67.16% charge dealing 100.4 damage.
