It will detonate instantly when within the explosion radius of other incendiary items, such as the Unstable Ordinance or Uncle Sam's Blam Blams, or when in direct contact with the Miniature Sun.
It has a small, disc-like shape with a black rim along the edges and a black and yellow hazard sign in the center. It bears a small antenna and a red light on its side, which flashes as it beeps.
