The tendy boi because of a sory about some guy who was dumped into a river that makes you invincible all his body was submerged except for the heal of the foot so later when he was older there was a war he refused to fight in it but when one of his friends died in the war he fought in the war so remember he was invincible everywhere except his heal of his foot so an arow struck that heal and he died so a tendy boi would win.
