Boulder traps

 are Traps in Knight Trap. Boulder Trap buttons have a white circle as the icon for the Button. Although Boulder Traps have Brick buttons, they use more of the usual wooden buttons for there traps. When a Boulder Trap is activated, a Boulder from either the left edge or right edge of the screen will roll on. Unlike other weapons, Boulders have the same appearance no matter what side they come out of.

Boulders released by Boulder Traps are made up of just tan coloured stone
