Goo Tuber

The Goo Tuber is a main weapon in Splatoon 2. This weapon can hold a full charge for an exceptionally long time in comparison to other chargers, being able to hold a full 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. 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.
