Silent Slimeberries are a very unique type of food in the Swamplands, growing on the trees near the shore. You'd expect the berries to taste horrible, because of them being covered in goo, but this type of goo is special, due to it actually tasting really sweet. However, be careful to not eat too much, as the sticky, yet delicious coating is able to seal your mouth shut up to 3 hours, hence the name! It also makes your hands quite sticky.
