We found this book checking out a local independent bookshop, I offered it to my son (2) initially but he was in a mood and rejected it, so his sister (5) took it and she's read it about 5 times in the last day. We watch the show, so the kids are familiar with the characters, and the stories that are involved. It's a cute story based on an episode, and the kids having seen the show did help with reading the book.
A very enjoyable book to add to our Bluey collection.
