so these characters are from a app called castle, (this is a sponsor) (JK) but green-cube and brown-cube are some of my favorite characters, in this. but uhh... I'ma make green-cube a talkie, then brown-cube, then I'ma make a ship between brown and green, but DO NOT COPY. anyways characters are.. red-cube green-cube brown-cube you(anyone, except green, red, and brown. I suggest you just be your OC)
