I love spiders. When I was a kid, I used to own a pet spider which I named "Red Baron", to whom I dedicate this piece, RB1.
RB1's abdomen is a container of dental floss. It's attached via magnets for easy and snappy access.
Yes, RB1 is useful! At least I know where to find a dental floss! That is, if i know where RB1 is! :)
