Ranged Turtle

A Ranged Turtle Is A Turtle With A Bow That Can Shoot Enemies When Loaded With Arrows
Crafted By Putting A Bow Somewhere Around The Turtle
(Its Basically A Melee Turtle With A Bow Instead Of A Sword)

You mean a turtle sending redstone pulses to a dispenser?

while true do
	redstone.setOutput("bottom", true)
	redstone.setOutput("bottom", false)
end

there is an addon mod somewhere which adds a range turtle (I think)
