If you know me and my few Mr. Men Reviews, then you can possibly imagine what I have to say on this. Like with the previous two I talked about (the second and third one), this is a very cute one. I think the simple Story of those are very delightful, and this one really uses the fam to a cute effect, with 13 basically wanting Yaz to have a great Birthday with a cake. 

What more is there to say with this one?
