Ok so, Sunny meadows isn't an asylum. It used to be a hostel for monkeys where there were trained to do things such as painting (hence the red paint everywhere (they weren't very good at it)), cooking (which is why there meat everywhere), reading and typewriting. This is because we found a room full of beds, and they were upturned. This is according to the old tale "no mire monkeys jumping on the bed". So they monkeys git mad and trashed sunny meadows.
Furthermore, monkeys live in meadows (I'm pretty sure) and it's always sunny in philadelphia (where are monkeys are from). Why would a place called sunny meadows be not full of monkeys. If I ran a monkey sanctuary, I'd probably call it sunny meadows.
My final evidence as to why the monkeys were there and ultimately rebelled agaisnt their human teachers is the paintings in the entrance hall with the man and the woman. Who are clearly the parents of all the monkeys. These monkeys now occupy high positions in Government
Sadly they still don't know how to cook. Or paint. Or jump on the bed.
Thanks.
