UNDERTALE - Pacifist Run Sans Battle

I thought "The Song That Might Play When You Fight Sans" was too good to go to waste. (thank you to melissachao @ tumblr for grabbing me the sans sprites) EDIT 3/14: This is a fanmade animation, made in Flash CS3. The other Sans Pacifist Fight (a fangame made by XYZ https://www.youtube.com/watch?v=deBGe...) is a separate Thing and was also made about a month after this one. Please don't get them confused! (and please don't harass the creator of that fangame either)
