To save and comfort Windy, the Giant Saver invited Windy to the supernatural research institute. Don promised Windy that Elena would be saved. After leaving the supernatural research institute, Windy told her brother the whole story. Under his sister¡¯s begging, Zoe decides to rescue Elena. With the help of Giant Saver team and Zoe, Windy saved Elena, but the flying-sand-and-stone elf fell into Seaman¡¯s hand. Soon the Seaman turned it into demon. Under the lead of Seaman, the flying-sand-and-stone demon gave rise to many troubles. With the combined efforts of the treasure-searching brother and sister and the Giant Saver, Seaman was defeated and the flying-sand-and-stone demon was controlled. Zoe and Windy delivered the flying-sand-and-stone elf to the supernatural research institute. Don invited them to join the Giant Saver, but Zoe refused.
