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.
