"....and yet, far down in that hollow cavern under my breastbone, the one that fills with the sensation of thousands of small screaming animals clawing their way to the top of the heap when I suffer the anxiety of doing my taxes or filling out student loan paperwork, or smell a Con on the horizon--far down in the bottom, heretofore empty, a lone tiny animal just trudged into view. It is a vague, nondescript, rounded little animal, a colorless hamsterish Anxiety Creature, eyes squeezed tightly shut, with stubby limbs and tiny, scratchy little claws.
"And it just screamed."

phrasing of the first half of that first paragraph on the DeviantArt
page where the creature is
illustrated;
if you requote this (and I myself am requoting from
metaquotes),
take a look and pick the version you like best.)
