The Sticky Bomb is an item in the Worms series which works similarly to the Grenade, but it sticks onto a surface once it comes into contact with something. It has a timer on it, so it will count down seconds until detonation, after which it blows up. Even if it hasn't sticked onto something, it will explode when the timer has expired. Like most weapons, the sticky bomb cannot detonate if it falls into water. So far, it has only appeared in Worms 3D.
Worms W.M.D. announced that the sticky bomb will return as "Sticky Grenade".
