The Watro (canon model name) is a form of creature encountered in Cry of Fear co-op. Not exactly an enemy and more of a hazard than anything else, a Watro is a large body of flesh with a large arm protruding from it -- several faces staring blankly from its mass.
The Watros are only encountered in the official Cry of Fear co-op campaign, where multiple Watro are fought at the docks. They will remain dormant underwater until the player approaches too closely to their hiding place. This will cause them to emerge from the water and wait for the players to come within range before striking at them, dealing a considerable amount of damage.
This creature has a great resemblence to the Human Flower, which is in reality a larger version of the Watros. Unlike its larger brother however, Watros can actually be killed by small arms fire.
