Red Hot Chilli Worm
From Worms Knowledge Base
The worm eats a chilli pepper and becomes red hot. The effect of this is that any worm that touches him suffers a tiny amount of damage, ending their turn. A big question is whether the red-hot state is on or off while the affected worm is taking its turns. If it's off, then the worm is only passively dangerous, but if it's on, then it can do repetitive damage to other worms by repeatedly touching them. This may sound like overly easy damage, but if it's only a couple of points at a time, and if the harmed worm recoils and moves away, then it could take many seconds to notch up big damage. Unless of course the worms are in a tight hole, in which case an effect similar to that of a petrol bomb can be achieved.
