March 22 Rail ferret 'took London train'

Sweet I'm tasting everythings fresh and rancid, dodging the hoardes of people and chasing the flies, right into my gulllet. Blinding the noise and the smell and the sounds in this manor. Needed to mix with a better class of riff raff, escaped the grass and the cows and down the drains I go. Sharper than before up top but camouflaged by a duller coat, my gums ripped from aluminium cans but the broadest smile.
Come here, look into my eyes, I can't promise not to bite.
