The Icicle is a weapon from the Ninjago series. It is a long silver spear with a large, mostly triangular blade at the tip. It is described as being very long, "extra sharp," and infused with the element of Ice, allowing it to freeze enemies solid with a single strike.
Cold to the touch, this extra long, extra sharp icy spear is a real treat. While not made for the desert, it does make a cool dessert. Just dip the Icicle into a Skulkin, and you’ll have the ultimate popsicle.[link unavailable]
