I love Max and Ruby. So bunchy and cute! This was a favorite from when I was younger. Our younger cousins were the right age at the time for the Max and Ruby TV show, and really reminded us of Max in this story. In fact "Again says Max" is a family quote, and used often!
As a board book, there's very little text, so when reading it for storytime, I did fill it out a little. Still, plenty of opportunity for emphatic exclamations from Max, though. For a one-on-one read, you could add as much or as little as you wanted, depending on your reader's age. We read it as part of a storytime on birthdays.
