They will be part of the overall exhibit, but not part of the walk-through.
I have just looked at the planning application papers again; unless plans have changed, there is just a single enclosure i.e. the main walk-through. Does this mean that the aye-ayes are going to be in an adjacent part of the Clore? Are they going to be on view? Are they going to be on a normal light cycle? Interesting.
I am still recovering from having my mind boggled by the idea of an aye-aye walk-through. It would be like building an aviary for emus and/or like letting school kids play darts in the National Gallery
