Goo Tuber
From Inkipedia, the Splatoon wiki
The Goo Tuber is a Charger revealed for release in Splatoon 2. It can hold a full charge for an exceptionally long time in comparison to other chargers. This allows players to get to a better vantage point or sneak up on enemies with a full charge. Its charging time and range seem to be comparable to a Splat Charger.
