I am the host.

To trigger a dog-shaped house in the northwest of Blissful Valley (that is, Ziyun District in the map), we must first find Dr. Doll in the south of the western continent, and then send it to the Little People Hall. When you go out, get off and walk to the northeast corner, and you will find a dog house, where you can find the X-shaped tube and the heart-shaped tube in the transmitter of Banana Research Institute. According to the requirements of the left-eye heart-shaped tube and the right-eye X-shaped tube, we will find someone to assemble it with the doll doctor, and then we will come to where the dog house is.
