Mad Cows

The Mad Cows were introduced in Worms: The Director's Cut. Their main special ability is that up to five of them can be sent out at a time.

Description
The Mad Cows work in a special way, the player can set how many cows are sent out depending on how many cows they have. If the player has 3 cows, they can send out 1 to 3 cows, and if they have 5 or more, then they can send out up to 5 cows. The amount of cows sent out is subtracted from the amount of cows that the player has. An example of this is that if the player has 5 cows and sends out 3, then they will have 2 cows left.

The cow itself will walk straight forward, exploding as soon as it comes in contact with a worm, an Oil Drum, or the terrain. A single cow inflicts 75 points of damage onto a worm, the same amount as the Dynamite and the Sheep. This weapon itself proves the phrase “power in numbers”. If it's used properly, the player can take out a group of worms.

Trivia

 * In Mayhem and Clan Wars, the cows are reintroduced as the Bovine Blitz.
 * In Worms 2, there is a weapon similar to this known as the Cloned Sheep, which sends out Sheep instead of cows, and is also more useful because the Sheep can be detonated manually.
 * In Director's Cut, the Cows not only moo, but they also bark like dogs and cluck like chickens.
