A happy morning was struggling to find its way into Rat's bedroom, but Rat
was feeling miserable. Not wanting to get up and not wanting to stay in
bed, he knew he was in for another case of the bathrobe blues.

The bathrobe blues are when you don't wash your face or comb your
whiskers and just mope around all day long in your bathrobe. Rat was
good at this. He did it every day.
