Caliban lives!

So...it has been a long time since we have seen Caliban, our one eyed possum. I was beginning to think he was gone for good but tonight he turned up again in the pear tree outside Blue Moon. While I was taking this picture Will heard the pump going down by Frogknot and we discovered that 'something' had turned on the shower tap down behind Frogknot. The shower head was hanging down, which it does when possums use it to get down off the roof to try and get at the soap. 'Something' must have then clambered further down switching on the tap. The pump must have been going for hours. We have lost quite a bit of water from the shed tank, something that we could do without at this present time, but it is still about 3/4 full. I wonder if Caliban knows anything about it? He wasn't saying anything though if he did.
