Indonesiaball Polandball is Underball's Sans.
Polandball is a ball with a red top and a white bottom, in this AU His pupils can be white, black, blue or orange, just like Sans.
Poland uses plungers and Hussar Blasters as a counterpart to Sans's bones and Gaster Blasters but cannot into control gravity, because he cannot into space.
Likes telling jokes about politics. Unfortunately, it annoys his brother, Hungary. Lazy as heck. Poland wants to go into space, but is unable to do so. He also feels threatened by Russia and Germany.
