Announced today as part of the update to ZooMumba, you will now be able to upgrade various habitats around your zoo. Not only will they look cool, they will also improve the life of your animals and bring more visitors.
Because these upgrades are not just for you, but for the animals, you will now gain more experience points for animals living in these upgraded habitats. They are getting taken care of, so naturally they are happier! Each one can be upgraded up to five times and can be built starting at level 3.
ZooMumba is a browser simulation game where you are the director of your very own zoo. Build fun environments for wacky animals in a colorful, enjoyable gaming environment. Show your zoo off to others and earn points or try to top the leaderboard for having the best zoo around!
