Happy Dozer is the first skin inside the 'Happy Collection' and is made with Dozer lovers in mind. Install the skin by placing the 'Happy dozer' folder inside your 'mod_overrides' directory. Once you've installed the skin, it will be available to use for the Micro Uzi SMG. If you'd like to use the skin on other weapons, you can use the mod 'Super Duper Skin Swapper'.
PS: If you like the skin and would like to support me and view more of my content, you can check out my steam workshop here.
