Overall: 4 out of 5 stars
Best friends Andy and Terry get to play all day in their amazing 13-story treehouse. What could be better? Unfortunately, they are supposed to be writing a book, but keep getting distracted by their marshmallow launcher and see-through swimming pool and sea monkeys that turn into evil mermaids. It turns out that at the end of their adventures, they have more than enough to fill up their book.
