A transparent 'blob' about 2" square on my doorstep with a damp patch round it (looks like something was melting) but been there 2 days and finally I plucked up the courage to pick it up (with 2 layers of kitchen roll) & put in bin. Felt like a lump of jelly!! We thought maybe an incredibly long phlegm (we're at least 15 feet from the road) but my DS just suggested could be a slug nest!!! That is my worst nightmare - please tell me it couldn't be!..... could it??
