3. Banana Bomb
What is a banana? To you and me, its a fruit typically grown in the Caribbean, rich in potassium and covered by a skin immortalised in countless slapstick skits. To warring worms, however, the foodstuff is one of the most rare and devastating explosives in existence, capable of destroying entire teams in an instant. Why the innocent (if slightly phallic) banana and not some other foodstuff? Who knows? But it certainly made for priceless school playground scenes in the mid-nineties when dinnerladies were completely befuddled at the sight of children lobbing their lunchbox bananas at each other.
