When exchange student Mai Le comes to Crystal Cove, she draws the affection of Shaggy. A dinner party hosted by the Blake family is interrupted by the Red Wizard warning to stay away from the Dragon’s Heart which he has sworn to protect at all cost. Later, Mai Le and the gang come under attack by the White Wizard who is after Mai Le’s ring, but then the Red Wizard comes to the gang’s rescue but is too late to save the ring from the White Wizard. The Red Wizard turns out to be Mr. Chen, the owner of Chen’s Internet Café and Tea House. He reveals that now in possession of all four rings, the White Wizard is able to open the Jade Dragon’s Heart, which is a priceless ruby, but they manage to trap him. Afterward, Mai Le says she has to leave on an airplane, prompting Shaggy to try and say goodbye in the airport. However, it is then revealed that Mai Le was using the gang to steal the Ruby for herself, and tries to flee on a boat. Shaggy catches on and lures her into a net trap on the boat.
