These are adorable. My favorites include Lethargic, Envious, Cold, and Drunk.

>>The idea with Envious is that the pigeon wants tiny hands and the rat wants wings; it makes me want to make a pigeon mood theme as a compliment to this one!<<

You should totally do a pigeon theme for next year's round! :D I love the little neck-rings. And there are SO MANY kinds of pigeons -- different shapes, colors, some of them do stunts, etc. You could use a Tumbling Pigeon for Excited, a Homing Pigeon for Homesick, a white one for Blank, etc.
