Interesting Facts about Animal Kingdom

[Simba's Mom]

To encourage the lions to sit proudly up on the rock for the Kilamanjaro Safari ride, which makes for great guest picture taking, the rock is heated in the winter and cooled in the summer for the lion's pleasure.

And when they first opened AK, there was a fan to help cool the rock (I don't know if there is now). On some days, the guests would see the lion's "ruff" blowing in the breeze-only problem, there was no breeze-it was just the fan blowing.
