I'm guessing it was something created by one of her direct managers. I doubt it was approved by anyone higher than that land's proprietor/area manager, but things like that don't typically need to get approved by higher ups either, since each land can - to an extent - make many small decisions on their own. Everyone in on-stage roles - as far as I know - got trained on an official, company approved "wildlife update." Her management probably just thought they'd be a little more specific with what they wanted CMs to say when guests ask specifically about alligators. I like that they were trying to give CMs something consistent to say, but I think whoever wrote it was incredibly misguided as to what he/she thought would be best to tell guests. There are soooo many better ways to answer guests' questions about the wildlife than to flat out lie to them!
