What's the difference between Alien House II and the first one?

The Tang family has a very important task in this season-defending the earth and preventing Pluto from invading. All this stems from the "obedient" nanny, a new member of the Tang family. The appearance of "obedient" is a handsome guy in his twenties, but his real identity is Pluto's first warrior. Under the care and influence of the Tang family, obedient finally changed from a militant who was bent on lurking and waiting for an opportunity to fight back to a supporter of earth harmony who said, "The earth is my home, and we will protect it together." In addition to obedient participation, Tang's life also changed in the second quarter. The security manager of the Tang Dynasty ended his career and was fired from the supermarket. He actively re-employed and finally became a black man, responsible for the mediation between aliens and earthlings. Beautiful fruit finally took the step of employment and went to work in the cafe opened by Lulu's mother. Tang Buku and Kerr continue their childlike and fantastic children's lives in this family composed of aliens and earthlings. In this season, they have a Poké mon that can only be used to communicate with each other, Kerr's new invention-the communicator of "whispering" between good friends.
