When the Demon Bull King started to attack Megapolis, Pigsy took MK, Mei, and Tang to the boat to get Sandy's help. At the ship, they learned that Sandy became a peacenik some time ago. However, Sandy agrees to help the team by taking to Flower Fruit Mountain.
After Mei and Pigsy returned to the ship, the team became devastated for MK's loss until Mei stated that the Demon Bull King must be stopped.
