Animated adventures with Bob the Builder and all his friends as they construct an ecologically friendly town from scratch. Robert visits the valley to spend some time with Bob birdwatching. Bob has three jobs to do before he can meet him. Each job ends up taking far longer than expected. It's dark when he gets to meet Robert, but luckily it turns out that Robert had a great day. Also, Bob is just in time to see the nocturnal lesser-striped sunflower warbler.
