I can verify the sightings at both AK (in Africa) and also at Epcot on the holiday bus. I have a feeling we passed Baloo by when he was meeting and greeting in Main Street Square (by the station) Guest services (location's are marked on maps) is supposed to be able to track the characters down for you at any park, even if you are at another park. Presumably there is some sort of rota for where these characters are suposed to be that is available to guest services, I would try them over a general CM, as it might be difficult for a CM to leave his post so to speak.
