Bob the Builder: Project Build It - Series 4 - Dizzy the Walking Bus

Animated adventures with Bob the Builder and all his friends as they construct a new, ecologically-friendly town from scratch. Bob is putting up some new signs in Sunflower Valley to help people find their way round the valley. Dizzy has been asked if she'll be the walking bus and help the children get to school. Dizzy is so excited that she doesn't make a very good job of mixing the concrete for the signs. Spud tries to correct the problem but makes matters worse - causing Dizzy to get lost!
