Clamovin(Screaming vine/clamor vine)
A thick creeping vine that can cover hundreds of meters of land. It's generally found in darker, forested regions, but can grow in most low light areas, or any place that gets little or infrequent direct sunlight. It can, however, survive in marshy terrain quite handily, direct sunlight or no. It has sparse, but thick and fleshy leaves which are safe to eat and taste somewhat tart... and kelpy. They might be useful in neutralizing particularly salty soups, but aren't palatable otherwise. The vines themselves are woodier in consistency than your average vines, with a thick barked core reaching up from the center of each plant. The notable characteristic of this plant is that it creates a hissing or whistling sound by ejecting (typically) malodorous gas through small pores in the plants' surface whenever a leaf is damaged or pressure is applied to a vine. The gas appears to be inert in most cases, and is not itself harmful. The plant can only do so a few times on any given day, but it is more than sufficient for scaring away would-be predators in most cases. The efficiency of the plants gas production seems to depend on the soil around it; more alkaline and drier soil results in less gas, with the opposite being true as well.
The plant would go dormant during snowy months. Through Frowndelia(or throughout a climate's dry/cold season if it's hot/warm), one may see large flowers dotting the surface of the vines, similar in appearance to clematis blooms. The flowers create a powerfully sweet smell, with the petals being usable in confectionery items or for use as a sweetener when diffusing or brewing. After the flowers are pollinated, massive, round, and green hued gourds develop at the buds. As they mature, the outer layer of the gourds harden and become brown and woody, making them exceptionally difficult to breach by wildlife. The gourds carry the same air as the plant, so getting into them can be a rather unpleasant experience. If the temperature gets too cold, the gourds may collapse in on themselves, or explode with surprising force in high heat, dispersing the walls of the gourd along with its seeds rather effectively. Blunt force is also sufficient to cause the gourds to explode, so the fruit can be used as makeshift explosives, though they would only really be effective at pushing back or stunning enemies, and would need to be thrown at a stony surface.
There isn't much in the way of food that can be obtained from the fruit, but the smooth, fleshy seeds lining the walls of the gourds are large and dense. They are quite sour, but by dehydrating them and grinding them into a fine powder, you can use them in nourishing candies, or to simply use as a spice, or as a compact emergency food source. The seeds can be planted, but an individual plant takes up a massive amount of space relative to the quantity of seeds it produces, and is initially slow to develop. The plant can be directed to grow in a certain way, so to speak, using blocks to restrict its growth to specified paths. Though, if you're not careful, it may just grow over the obstructions you build.
