What zone do giant tube worms live?

In Worms Zone (a popular mobile game), "Giant Worms" are often a reference to players who have grown their worm to an exceptionally large size by eating food scattered around the map. The goal of the game is to consume as much food as possible to grow your worm while avoiding collisions with other worms. The bigger the worm, the more challenging it becomes to avoid crashing into other players, but it also allows for more dominance in the game. The game is known for its simple yet addictive mechanics, where strategy and agility are key to becoming the largest worm on the map.
