Ink tank

The ink tank is an object that Inklings use to store ink. It appears in all battle modes.

The ink tank is a cylindrical container made primarily of clear plastic, while its top and bottom are covered in green caps. Inklings typically wear an ink tank on their back during battle as a way to store ink. As Inklings use a weapon, the content of the ink tank visibly decreases. When an ink tank is nearly out of ink, weapons can no longer be used in their regular state, and a notification appears, stating "low ink!". Ink tanks can be refilled slowly by ceasing to use a weapon, or quickly by being submerged in a puddle of similarly-colored ink. While submerged, an ink tank icon will appear, displaying the current capacity of the ink tank that will disappear once the tank is full.
