Dotty with a crate.

Is Dotty a Fly river turtle?
And is she off somewhere?

Dotty is a Nile Softshell Turtle if I remember correctly..she(?)'s in the African Rainforest Pavilion

Are they moving her or are they just acclimatizating her for medical purposes in the event they need to take her to the Health Centre?

I've since been told by several people that the crates been there for a long time. I have no clue though what its for. He is not being moved or he would have been gone long ago. Could be a just incase thing like you suggested. Might even just be so simple as to show us how they move animals like Dotty.
