The 52-story treehouse is a fun book to read because there's lots of pictures and funny things that the characters say and do. For example when Terry trains the ninja snails or when the caterpillar eats everything that comes in it's way. My favourite character is Jill because she remembers Andy's birthday and makes a party whith all the animals. I wish that I had a Disguise-o-matic 5000 in my tree house. I would give this book a 4.5/5.
