About two weeks ago my girlfriend cooked me fish for dinner but i was late home so i didn't eat it. She threw it in the bin but about 2 days later we went on holiday and hadn't cleared the bin. We got back a week later and there was a perculiar smell around the flat. It wasn't gross or anything, just a smell i'd never experienced. I eventually realised it was coming from the bin and looked through the rubbish. At the bottom was a fat and bald black midget. He was wrapped in what appeared to be fish scales and covered in fish eggs which he was eating. I was so amazed i didn't even bother to ask what he was doing in my flat. He says that he has the power to turn decay into life, hence turning the mouldy fish into a new skin/blanket for himself. I don't really know what to think, any advice/help would be great.
