Sans may seem like a kind-hearted and broad-smiling character. But that doesn’t mean he can’t be pushy and determined when he has to fight someone! You can see that for yourself playing a new FNF mod dedicated to Undertale. Here you will be hip-hopping against Sans and you have to demonstrate a really outstanding musical talent to beat him. Move your fingers over the keyboard arrows in time with the rhythm and try to hit all the notes!
