After Kidōmaru summons Kyodaigumo, it releases an egg sac full of baby spiders roughly the size of a small dog. Kidōmaru then cuts open the sac, causing the spiders to rain down on his opponent. Each spider then spins a strand of webbing as they fall, thus encircling the opponent in webbing and immobilising them.
