Animal Enclosures were added in Wild!. Three fence types (wood, chainlink, and electric) are available, depending on what the animals require. These enclosed areas must also contain the appropriate habitat (each one spawns a zookeeper to feed the animals and clean up dung, although more can be hired from the Staff Panel). Observation areas must be installed for peeps to watch the animals, and they can be charged for admission just like any other ride. The Safari Jeep and Safari Train rides can enter and exit the enclosures, and animals can safely cross the tracks.
