Hades offers Pain and Panic one last chance to kill Hercules, so after learning from the Fates about the Spring of Canathus, a pool which reverses age, the two go to the Stymphalian Forest to retrieve some. Meanwhile, Hercules and his class are taking care of eggs – all but Cassandra, who ate hers. Pain and Panic squirt the water on Icarus, Pegasus, Adonis, Pain and finally Hercules, leaving Cassandra and Panic to take care of the new babies.
They travel to the Stymphalian Forest again to get more water to turn them back, encountering a giant snake and even more giant Stymphalian birds who want Cassandra to rescue their egg. After finally turning everyone back, Cassandra has learned to be a mother and Panic has learned to work with his enemies for once. Meanwhile, everyone pleads with Cassandra to not let anyone know she changed their diapers.
- The fire-breathing bull that Hercules fought at the beginning of the episode was likely a Khalkotauroi (also known as the Menaian or Colchis Bull), a bronze bull capable of breathing fire.
