During the communication with the fake rainbow cat, Lan Tu found that the change of the fake rainbow cat was abnormal, and he also found that Doby was not right. At this point, Dada, who was dominated by Black tiger, fell in love with Doby and others. Lan Tu was so worried about the fake rainbow cat that he was very anxious. So he wanted to tell Lan Tu the truth and let Lan Tu go to the foot of Tian Zi Mountain (where the rainbow cat fell off the cliff) to find an excuse to take Lan Tu away. Lan Tu thought over and over again, and finally realized Dada's painstaking efforts, and found Sally and Rainbow Cat. After learning the truth, he decided to let the rainbow cat move its hiding place.
