Koko and the Tunnel is book number five in the Chuggington Storybook set. I think there are six of these books which have been released so far in this particular collection, and though they are sold seperately, they have covers which match and look rather smart sat on the play room shelf. This book is available from Amazon for £3.59, though I have seen some good multi-buy deals around from places like the Book People which are definitely worth checking out.
This story is about Koko. a young Chugger who is still learning the ropes, falling victim to curiousity. She is told to stay on task and follow the rules, but she's too tempted by a mysterious tunnel to do so. She wanders off alone to explore, and there are of course consequences to this. All is well in the end, but the point of the story is to show young children that there was a reason why Koko shouldn't have wandered off without an adult!
The story is written in the same style as the others in this series, and I do think that all of these stories are a little on the long side. If you've got a very young Chuggington fan who is after some Chugger books, then I'd look to the much shorter board books instead of this. It's a full length bedtime story in here. I like that there are a lot of individual words typed in bold here and there which will catch the eyes of early readers and encourage them to join in though.
This is a bright and colourful story which makes use of the Chuggington animations from the show. They're all re-prints of the computerised cartoon series, so kids will instantly spot all of their favourite trains in this book. There is a bonus sticker spread in here too, which is pretty similar to the sticker spread which has been included in all the books in this series. They're nice stickers though and they're relatively easy to peel off too, so I think they're a nice addition. They could have put them on a perforated sheet at the front or back perhaps though, instead of making them a permentant fixture in the centre of the book (it looks a bit scruffy!).
If you've already read the Christmas annual, then you'll already have read the short version of this. I don't think it's really worth paying £3-£4 to get this slightly lengthened version and a few stickers, but if you've got a die-hard Chuggington fan on your hands, have bought the other books in the series, or have never had the annual - then this might be one for you.
