Squid ink is used to make Squeeze, an exotic foraging item. Squeeze is rarely seen in the wild, but if you can find it then harvesting it will assure that you catch more fish while fishing! Squeezes use also blacklisted by most seafood stores, but if you want to boil some up at home all the better! Restrictions: Squid hatchery/Fish hatchery area not allowed. Squid ink obtained from green slimes are not able to be placed in inventory.
