Marine Mania is the best expansion pack out. The graphics are wonderful. I have learned a lot about marine animals since I got it.
-Add 20 beautiful marine animals (mammals, fish, reptiles).
-The game also comes with a useful tool-- the eyedropper. It is used to easily duplicate objects.
- Now the trees, bushes, and grasses now sway with the add of the expansion; making it look even more realistic as you tour your zoo.
You can now go under water in the ponds, lakes or tanks you construct. Even add koi to ponds.
- Train orcas, dolphins, seals and more to make incredible shows to wow your guests.
However...I would recomend it be a tad more realistic in some ways (carrots cost $50 ea., animals get stuck in the ground). The game itself should be about $20 (that's how much I got it for on sale). Do not get it if you don't have a NEW computer. Older ones can't handle the game. Overall I give this game a high rating and recomend it to animal lovers.
