Near the end of Series 1, Topsy and Tim have moved house. In the intro for Series 2 however, while they've moved house no move than a few miles away from their old home the placement of Topsy and Tim's family car and themselves are still in the same area as shown on the Series 1 intro.
I love the positive energy of the show. The parents are fun and Topsy and Tim are adorable. Kids will learn a lot of different skills. It's a program the family can watch together without concern. There is nothing outdated that I saw. If you believe in family and can appreciate the value in clean living, you will not be disappointed.
