These are body parts and sprites used by some AGK parodists like Thomas Cartoon, Atarster, Cansin13, Shiyamasaleem, Atekuro95 (formley DatLampGuy), Dipsy57_YT (A.K.A, DatDipsyGuy), and many other AGK parodists. You can use these sprites for your series, too, unless if you give credit to the owner of the sprite used.
