I liked this expansion pack. It has a lot of fun animals, buildings, and decorations.
My only complaint is the maps. There are not very many of them and they all have challenging weather which can be a hastle (especially if you are trying to keep plants alive). Most maps do not have a lot of precipitation which means the gardener constantly needs to water them (and he doesn't do a good job). They are also either really hot or really cold. My plants always end up dying.
The expansions for WLP2 don't tie together very well. For example, if I wanted to play Farm World, I could still get the Crazy Zoo animals, but thats it. None of the plants, buildings, or decorations would transfer to the other expansion, which is kind of annoying.
Also the icon is a creepy looking clown.
