What an interesting fellow!
We saw him in the drain outside the kitchen this morning, looking more like a dry yellowing Autumnal leaf than something alive. Until the water from the bathroom above wooshed down and enveloped him. He suddenly twitched, obviously revelling in the joyous feeling of the wet coolness, and then returned to his absolutel stillness once more. He wasn't put out by the flash of my camera, just watched and waited ( probably for the next 'woosh').
Don't know if he's a frog or a toad, but he certainly has made himself 'at home'. He has an almost 'alien', owl - like appearance. Mmmm, maybe I'll draw and paint him one day.
Watch out little 'fella', we may ask you to pay rent!
