BALL SQUIG There is an unlucky little creature known as a Ball Squig that has the great misfortune of looking exactly like a standard Blood Bowl ball. Often prone to hibernation, these balls are brought onto the pitch by accident and awakened by the kick-off when an unobservant player punts its backside halfway up the pitch. At the beginning of the kicking player's turn it will try to move towards the nearest pitch edge directly. Any player in the way will be blocked. If the Ball Squig leaves the pitch, it is thrown back in by the crowd as normal. Anyone holding the Squig has a -1 AG modifier to all actions because of its squirming. Its stats are:
