Officially, the giant panda's names were Quin Quin and Quan Quan as Meaghan said ... pronunciation and phonetic spelling are probably the root behind all of the differences!
Re: Littlefootland
Before the redevelopment of the front area, there used to be a very large lawn (the "main meadow") where the Waterside Theatre and Splash Island are now. A pathway went directly from the front entrance (by the turnstiles) to the Siberian tiger exhibit, past the pony rides and Littlefootland (not sure what the capitalization was for it!).
The entrance to Littlefootland was about where the entrance to the current kids zoo is. There was a round cage with wild turkeys on the right side between the path and waterway. The current "bird barn" used to house most of the domestics (the pictures with the bright yellow rail fencing were taken in the barn). A playground (with the jumping graphics described by Meaghan) were between the pony rides and barn, along with a series of aviaries which housed a variety of birds (including bald eagles, kookaburras, and kestrels). (I think they show the aviaries with a kookaburra in a Zoo Diaries episode). The site of the current Group Events Tents (Stingrays) had a variety of yards for other domestics (including miniature horses and rabbits), as well as a contact yard with sheep and/or goats).
The Group Events Tent used to be where Splash Island is now, but oriented in a North-South (rather than East-West) direction. Yes, this is where the first dinosaurs and sea creatures were.
