In a mixing bowl, combine the softened cream cheese, mayonnaise, Worcestershire sauce, hot sauce, and garlic salt using a hand mixer until the texture is smooth and fully blended. Stir in 1 tablespoon of the chopped scallions, reserving the remainder for later, followed by the shredded mozzarella and imitation crab. Transfer the mixture onto a sheet of plastic wrap, shaping it into a rough ball. Wrap it tightly and chill for at least 4 hours until firm. Once set, form into a neat ball and coat the surface evenly with the reserved chopped scallions. Serve alongside your preferred crackers.
