Twig and Turtle are two sisters whose parents have just moved into a tiny house! The family has done some major downsizing -- the kids even had to choose just five toys they could keep, and now they have to clean up after playing with their toys. Both girls are also adjusting to a new neighborhood and new school. Turtle, the younger girl, seems to be adjusting well at school, making friends and having a good time. But for the older girl, Twig, things are a bit harder. She's self-conscious about having few clothes in rotation and being new in general. Twig is also missing their Great Dane, Bo, whom they had to leave at their Grandma's because of the tiny house. Twig decides that the she will convince her mother to let Bo move in with them again.
