The listing, Dinasoar Car Tracks with 2 Cars has ended.
This is 8 pieces of puzzle tracks with 2 cars, the blue car is a wind-up & the yellow bus runs on a battery (included) I bought this at a Garage Sale last summer for my grandson. I thought a piece was missing so went back to the sale, she had 3 more but they all had 8 pieces. Guess I didn't put it together right (never was good with puzzles!) Anyway, guess you can fix it several ways. It's a very intertaining toy.
