New pygmy hippo enclosure

I may be being stupid but what is this? is it indoor viewing?

Yes it is. On the sketch below it is the view through to the left hand side of the pool with the foliage in front.

On your sketch of the inside house, what has happened in the lower righthand corner? This used to either one or two 'dens' I think- have they been removed so people can now look through the walls to the outside?

This old antelope/camel/tapir house seems to have had another sort of partial makeover to turn it into a hippo house now.

Yes the lower right hand corner is all empty space for viewing with a window looking out onto the paddock.

great thanks, I did see the sketch, but failed at working out which bit was which
